Considering the carbon trading mechanism and consumers’ preference for low-carbon products, a game decision-making model for the low-carbon e-commerce supply chain (LCE-SC) is constructed. The influences of commission and carbon trading on the optimal decisions of LCE-SC are discussed and then verified through numerical analysis. On this basis, the influence of carbon trading on regional sustainable development is empirically analyzed. The results show that the establishment of carbon trading pilots alleviates the negative impact of unfair profit distribution. Increasing the commission rate in a reasonable range improves the profitability of LCE-SC. Nevertheless, with the enhancement of consumers’ low-carbon preference, a lower commission rate is more beneficial to carbon emission reduction. The total carbon emission is positively related to the commission rate. However, the unit carbon emission decreases first and then increases with the commission rate. The influence of the carbon price sensitivity coefficient on the service level is first positive and then negative, while the influence on the manufacturer’s profit goes the opposite. The empirical analysis confirms that the implementation of carbon trading is conducive to regional sustainable development and controlling environmental governance intensity promotes carbon productivity.

With the gradual popularity of online sales and the enhancement of consumers’ low-carbon awareness, the low-carbon e-commerce supply chain (LCECSC) has developed rapidly. However, most of the current research on LCECSC assumes that the decision-making body is rational, and there is less research on the irrational behavior of the e-platform altruistic preference. Therefore, aiming at the LCECSC composed of a single e-platform and a single manufacturer, this paper establishes two basic models with or without altruistic preference. Additionally, this paper combines the characteristics of online sales and assumes that altruistic preference is a proportional function of commission, then establishes a commission-based extended model with altruistic preference to further explore the influence of commission on its altruistic preference. The current literature does not consider this point, nor does it analyze the influence of other parameters on the degree of altruism preference. By comparing the optimal decisions and numerical analysis among the models, the following conclusions can be drawn that: (1) different from the traditional offline supply chain, the profit of the dominator e-platform is lower than the profit of the follower manufacturer; (2) when the consumers’ carbon emission reduction elasticity coefficient increases, service level, sales price, carbon emission reduction, sales, supply chain members profits, and system profit increase, ultimately improving economic and environmental performances; (3) the altruistic preference behavior of the e-platform is a behavior of ‘profit transferring’. The moderate altruistic preference is conducive to the stable operation and long-term development of LCECSC.

This study considers two incentive mechanisms, the reward-penalty mechanism (RPM) and the altruistic preference (AP). An E-commerce closed-loop supply chain consisting of a remanufacturer and a network recycling platform (the platform) is constructed to examine the recycling service and the quality improvement. Three models are developed to study how RPM and AP affect recycling decisions and models are also extended to multiple recycling periods to explore how profits and recycling quantity change with time under two incentive mechanisms. The findings show that the RPM and AP help to improve recycling service level, quality improvement level, and recycling quantity. However, under the influence of the platform's AP, the RPM is not always conducive to raising the recycling price. The influence of the platform's AP on recycling price is affected by the quality improvement cost parameter. Only when the RPM intensity is higher than the threshold, RPM can benefit remanufacturer. Consumer surplus is higher with AP and RPM both considered, so consumers can benefit from the two incentive mechanisms. The social welfare first increases and then decreases with the RPM intensity, but increases with the AP coefficient if the reference point of the remanufacturer's profit is small. Although the AP causes a decrease in the platform's profit in the early period of recycling, it can increase recycling quantity and the remanufacturer's profit over time. Moreover, both the remanufacturer and the platform can benefit from two incentive mechanisms and eventually obtain higher profits over time.

Explosive enterprises’ immoral behaviors in the online shopping market are widespread and have not been effectively solved. Especially in developing countries, there is a direct relationship between massive immoral behaviors and the inefficiency of government supervision. Using an evolutionary game, this paper finds that immoral behavior is more likely to spread in online markets than in traditional markets. Only when government supervision and punishment are large enough and government’s punishment for the illegal enterprise exceeds extra supervision costs that government pays, explosive immoral behaviors can be curbed. Additionally, consumer support is an essential factor in improving the efficiency of government supervision. This study sorts out the interactions between e-commerce market participants and the government, obtains a path to achieve efficient government regulation, and offers management insights. The findings can serve as a reference for ensuring order in the emerging online shopping market and can also provide theoretical references for future related research.

Considering that the manufacturer produces normal products (NPs) and low-carbon remanufactured products (LCRPs), this paper studied the production decisions under capital constraints and the Carbon Emission Permits Repurchase Strategy (CEPRS). The direct selling model and supply chain model are constructed respectively and optimal decisions are given. On this basis, the influences of CEPRS on optimal decisions and corporate performance are analyzed. This study shows that for the capital-constrained manufacturer, adopting the CEPRS is conducive to promoting the production of LCRPs. In the direct selling model, a higher end-of-period carbon price is not always beneficial for the environment. In the supply chain model, as the end-of-period carbon price increases, the low-cap manufacturer tends to lower the wholesale price of LCRPs, while the high-cap manufacturer tends to increase the wholesale price of NPs. A lower carbon cap is more effective in controlling carbon emissions, while a higher carbon cap generates a higher profit. Moreover, the manufacturer’s preference for operation mode is affected by the carbon cap. Specifically, the low-cap manufacturer prefers the direct selling model, while the high-cap manufacturer prefers the supply chain model.

This paper reviews the decisions, coordination contract, and altruistic preference of an e-commerce supply chain (eSC) composed of a manufacturer and a third-party e-commerce platform (platform). The research derives optimal decisions in a decentralized model with altruistic preference; it is indicated that altruistic preference can help increase the sales price and sales service level. Although the platform’s altruistic preference is not beneficial to its own profits, it can help increase the manufacturer’s profits. Moreover, when the degree of altruistic preference is kept within a limit, the profit of the decentralized system is higher in a model with altruistic preferences, which indicates that altruistic preference can contribute toward maintaining a friendly, harmonious, and cooperative a relationship between the platform and manufacturers. Contrary to a traditional offline supply chain, where the sales price is the lowest in the centralized model, the sales price is highest in a centralized eSC model. In the proposed coordination contract, the platform with a certain degree of altruistic preference offers zero-commission sales service and charges a certain amount for a fixed professional service fee. The proposed contract is more applicable to products whose market demands are less affected by sales prices and more affected by the sales service level.

Considering the peculiarities of logistics in the electronic commerce (e-commerce) supply chain (ESC) and e-commerce platform’s altruistic preferences, a model including an e-commerce platform, third-party logistics service provider, and manufacturer is constructed. Based on this, three decision models are proposed and equilibrium solutions are obtained by the Stackelberg game. Then, an “altruistic preference joint fixed-cost” contract is proposed to maximize system efficiency. Finally, numerical analysis is used to validate the findings of the paper. The article not only analyzes and compares the optimal decisions under different ESC models, but also explores the intrinsic factors affecting the decisions. This paper finds that the conclusions of dual-channel supply chains or traditional supply chains do not necessarily apply to ESC, and that the effect of altruistic behavior under ESC is influenced by consumer preferences. Moreover, there is a multiparty win–win state for ESC, and this state can be achieved through the “altruistic preference joint fixed-cost” contract. Therefore, the findings of this paper contribute to the development of an e-commerce market and the cooperation of ESC members.

A low-carbon supply chain formed by a dominant retailer and a small and medium-sized manufacturer (SMM) is considered. Because the SMM faces the high cost pressure of adopting carbon emission reduction (CER) technologies, the retailer may take an altruistic preference for the long-term sustainability of the chain. Three decision-making models, centralized, decentralized without altruistic preference, and decentralized with altruistic preference, are constructed to compare decisions and profits of both parties. Since neither decentrailized models can lead to a coordinated solution that is incentive compitable, a coordination contract, referred to as the cost sharing contract with altruistic preference, is proposed. Numerical study shows that the altruistic preference can help increase the SMM's profit and system efficiency but decrease the retailer's profit. The coordination contract requires the retailer to adjust the unit profit and share more than half of the CER cost. It is found that the wholesale price is the lowest in the coordination contract and the comparison of unit profit depends on the coefficient of CER cost.

In recent years, manufacturers have been under pressure from consumers and the government in terms of environmental awareness and corporate social responsibility (CSR). The CRS behavior regulated by government subsidy is limited understood and needs attention urgently. In this study, three closed-loop supply chain (CLSC) models, including one decentralized decision-making model without fair concerns, one decentralized decision-making model with fair concerns, and one centralized decision-making model with fair concerns, were designed to for understanding the influence of government subsidy, CSR coefficient, and fairness concerns on decision-making by comparing optimal solutions of these models. Proportion of government subsidy was utilized as a coordination variable to design a joint contract of ‘government subsidy sharing and cost sharing’ and to coordinate decentralized decision-making. On this basis, two extended models, a CSR-based fairness concern model and a government decision-making model, were proposed. Finally, the models are verified by numerical experiments. Conclusions that we drew from this study. Our research shows that: (i) There is a threshold for the manufacturer's CSR, and CSR works only if it is higher than this threshold. Both the CSR behavior of manufactures and the fairness concerns of retailers can increase consumer surplus, retailer’s profit, and system profit but damage the leading enterprises' profit. CSR behavior of manufactures can effectively diminish retailer's fairness concern, but will reduce the efficiency of government subsidy to some degree which differs from past researches. (ii) The impact of retailers’ fairness concern about the profits gap is twofold. On one hand, it decreases the sales price and increases the consumer surplus in the forward supply chain. On the other hand, it decreases the price and quantity of recycling in the reverse supply chain. (iii) The centralized decision-making model has the lowest retail price of products, the highest the recycling price of waste products, and the highest system profit. (iv) After coordination, the retailer's share of profits increases as the fairness concern increases, but the feasible scope for coordination mechanisms decreases.

Considering the growing phenomenon of consumer returns and channel power struggles in e-commerce supply chains (ESCs), the ESC model is constructed and its equilibrium solutions are calculated and compared. Further, the consumer utility function is constructed to explore the impact of returns and dominant enterprises on consumer utility. Based on this, the “return cost-sharing and commission readjusting” contract is designed to maximize both ESC and consumer utility. Finally, the paper validates and further analyzes conclusions through numerical simulation. The main conclusions are as follows: higher return rates and return handling costs will reduce market demand and ESC profits, while higher salvage value of returned products will have a positive impact on ESC, but the above factors will not affect the online service level under decentralized decisions. The impact of consumer’s service quality preferences on manufacturer’s profits and e-commerce platform’s profit is determined by channel power structure. The impact of return rate on consumer utility depends on two factors: the decision-making model and the hidden cost of consumer returns.

Since environmental problems are becoming increasingly prominent, macro policies and social development have placed higher requirements on manufacturing enterprises to promote green transformation and upgrading (GTU) in China. Considering that different manufacturing enterprises choose different green technology innovation levels for GTU under environmental regulation, a game model between manufacturing enterprises and the government is constructed. The relationship between the green technology innovation level (GTIL) and the environmental regulation intensity is analyzed. Through numerical examples, the influences of environmental regulation and consumer preference on system decisions are further examined. Moreover, an econometric model is constructed to explore the influence that the environmental regulation exerts on the GTIL using panel data from the Chinese manufacturing industry. Our results show that the increase in environmental regulation intensity contributes to improving GTIL and promoting the GTU of manufacturing enterprises. Furthermore, as the environmental regulation is enhanced, the sales price decreases, benefiting consumers. Consumers’ preference for high-GTIL products is conducive to GTU under environmental regulation. Empirical analysis shows that there is a U-shaped relationship between environmental regulation and the GTIL. Only when the intensity reaches a threshold can the environmental regulation be beneficial to improve the GTIL and promote the GTU of Chinese manufacturing enterprises.

More low-carbon products help fight climate change and environmental problems. Governments consider encouraging the manufacturer’s initiative of producing low-carbon products by providing subsidies. However, when the manufacturer sells low-carbon products through the e-commerce platform, fairness concerns arise because of the profit difference. So, this paper builds game models to study decision behavior in the low-carbon e-commerce supply chain when the manufacturer receives government carbon subsidies and has fairness concerns. Our findings show that consumers’ preference for low-carbon products will be conducive to the operation of the supply chain. So it is necessary to popularize low-carbon products. The effect of government subsidies on supply chain decisions is different from fairness concerns. Government subsidies are positive factors in the supply chain operation, which can stimulate the manufacturer to make low-carbon products as expected and choose the high quality-high price development mode. This will help improve the profit of enterprises in the supply chain but cannot effectively stimulate the e-commerce platform to increase its service level. By contrast, the manufacturer’s fairness concerns are negative factors, which make the manufacturer prefer to adopt a low quality-low price development mode to improve their utility. This offsets the positive effect of government subsidies. It turns out that the profit of both node enterprises and the supply chain system has declined. But, fairness concerns are an important way to express the manufacturer’s demand. Finally, the joint allocation contract of cost and profit designed by comprehensively considering the effect of government subsidies and fairness concerns can make the supply chain coordinated. However, even as positive factors, only within a specific range do government subsidies help coordinate the supply chain, but not the more, the better.

With the rapid development of the cyber economy and green consumption demand, more and more consumers choose to purchase green products through e-commerce platforms. Considering the product green degree and the e-commerce platform's service, the paper studies the decisions and coordination of green e-commerce supply chain under green manufactures’ fairness concerns. The centralised model and the decentralised models with and without fairness concern are constructed and analysed with consideration of product green degree and service level. Then, the ‘cost-sharing joint commission’ contract is proposed to realise system coordination. Finally, propositions and conclusions are verified by numerical simulation. The results indicate that unlike traditional offline and dual-channel supply chains, the manufacturer's behaviour in response to fairness concerns can result in the decline both in product green degree and system efficiency but has no impact on service level. Under the centralised model, the product green degree is not the highest but is more affected by consumers’ green preferences. In addition, the product price and the service level will reach the highest under the centralised model. The increase in green technology investments can downsize the feasible interval of the contract, and the consumers’ green preferences can extend the feasible interval.

With the rapid development of the network economy, it is a marketing strategy to provide an extended warranty (EW) service. Considering the differences in the EW service providers and dominant enterprises, this paper proposes four kinds of decision-making models and aims to study decisions of the electronic commerce supply chain, including EW price, sales price, and service level of e-platform. Through comparative analysis and numerical analysis, this research shows that, among four decision-making models, the highest system profit can be achieved when the seller provides the EW service and the e-platform dominates the system. For electronic commerce supply chain enterprises, whether to dominate the system or to provide EW service, it is conducive to the increase of profits. When the e-platform provides the EW service, the conclusion is that who dominates the system is the one who gets more profit. However, when the seller provides the EW service, the conclusion is that who dominates the system is the one who gets less profit. When the EW service is offered by the dominating enterprise, service levels of the e-platform are lower.

For a low-carbon e-commerce closed-loop supply chain (LCE-CLSC), the influence of a government subsidy and a remanufacturer’s altruistic preference on the decision-making is discussed. Additionally, from the perspective of social value, decisions of LCE-CLSC are compared and analyzed. On this basis, the ‘Altruistic Preference Joint Commission’ contract is given to realize the system coordination. Finally, verify the models’ conclusions by the numerical analysis. The results are as follows: government subsidies improve the overall supply chain operational efficiency and the total social surplus. The altruistic preference behavior increases the revenue of the e-commerce platform and improves the efficiency of the LCE-CLSC, but is not advantageous to the remanufacturer. In addition, the effects of altruistic behavior on promoting the recycling of waste products are inferior to the effects of government subsidies of the same strength. Both the consumer surplus and the total social surplus are the highest under the centralized model. The increase in the consumers’ awareness of low-carbon environmental protections is seen to increase the substantiality of the contract negotiation space and the feasibility of the coordination mechanism of the ‘Altruistic Preference Joint Commission’ contract as well.

Taking the e-commerce platform’s fairness concern into account, three decision-making models of e-commerce closed-loop supply chain are constructed. Then, the recycling decisions under three models are studied and the impact of fairness concern is analysed. The ‘effort costs sharing contract’ is proposed to realise the coordination of the supply chain. Finally, the conclusions are verified by numerical analysis. The results show that the e-commerce platform’s fairness concern reduces own profit and the remanufacturer’s profit, and decreases system efficiency. The ‘effort costs sharing contract’ can realise the centralised model where recycling price of waste products is the highest, commission is the lowest, and system profit is the highest. In the coordinated system, the higher the proportion of remanufacturer sharing effort costs, the higher the profit of remanufacturer.

A capital constraint is an important factor which restricts the development of small and medium-sized e-commerce platforms. So, the influence of different ways of capital constraint relief on the pricing and service strategies of an e-commerce supply chain was investigated. In order to investigate whether the small and medium-sized e-commerce platform adopts a loan strategy and induces the manufacturer to share the service cost, four decision-making models were constructed. Then the supply chain's pricing and service strategies were analyzed. Following this analysis, we study the conditions for the manufacturer to share the service cost, for the platform to choose the loan strategy, and for a bank to induce the platform to implement a loan strategy. Finally, numerical analysis was employed to prove the correctness of our conclusions. The results show that when the manufacturer shares part of the service cost, the more self-owned funds of the platform, the more beneficial for the manufacturer. Moreover, it is highly advantageous to relieve capital constraints when the manufacturer and the platform share the service cost and the platform implements a loan strategy. Further, we obtain the effective range of a flexible loan rate which is conducive to the operation of the e-commerce platform.

In this study, we examine the impact of the dominant enterprise’s fairness concern on decisions in e-supply chains. Considering that the network platform’s service level obviously influences product sales, an e-supply chain consisting of a single manufacturer and a single network platform is constructed. In this setting, four models of whether fairness concern is considered by the different dominant parties are investigated, and optimal decisions of the four models are compared and analyzed to study the impact of fairness concern. The findings show that when fairness concern is not taken into account, the profits when enterprises are dominating system are higher than when they are not dominating system. When fairness concern is considered, the dominant enterprise’s fairness concern is beneficial to increase the subordinate enterprise’s profit, but it will reduce its profit. And when the network platform dominates system and considers fairness concern, the sales price and the service level are the highest, indicating that consumers can get an enjoyable shopping experience. To sales price, it is negatively correlated with the fairness concern coefficient if manufacturer dominates the system, while it is positively correlated with the fairness concern coefficient if network platform dominates the system. Regardless of who has the fairness concern, fairness concern can improve the service level and increase consumer stickiness.

With the rapid development of cybereconomy and the enhancement of sales service, many e-commerce platforms provide extended warranty service to alleviate consumers from worries about product quality when consumers purchasing products online. This study examines the decisions and coordination of the e-commerce supply chain where the e-commerce platform dominates and provides sales service and extended warranty service. The findings show that the centralised decision-making model is an ideal model because of the low sales price, high service level and high extended warranty price. With the increase of the consumers’ sensitivity coefficient to the extended warranty service price, sales price increases but extended warranty service price and service level decrease, the retailer’s profit and the platform's profit decrease. The proposed contract of ‘revenue sharing joint commission’ can realise the coordination of e-commerce supply chain.

In recent years, severe haze issue has affected every Chinese citizen and it has been attracting more and more attention from both researchers and practitioners. Enterprise is viewed as the culprits causing the haze, and so, it is also an important subject for preventing haze. The aim of the study is to find a government supervision mechanism that can encourage companies to actively prevent haze. Using evolutionary game, two kinds of government's supervision mechanisms are established, namely, “Centralized supervision” and “Long-term regulation”. The conclusion shows that “Long-term regulation” is better than “Centralized supervision”. Because long-term regulation has lower management costs and broader management scope in the long run. And the larger the ratio of the cost of enterprise’s abiding by the law to that of violating the law is, the more effective the “Long-term regulation” mechanism will be. As long-term regulatory mechanisms are required to pre-set air quality thresholds, government agencies should promptly adjust the value and make it public. In addition, increasing the initial proportion of enterprises complying with the law is crucial for supervision. And government should create an external environment to encourage enterprises to comply with laws.
