Biopesticides are perceived as a feasible alternative to chemical pesticides, providing an effective approach to pest management while mitigating the undesirable effects of chemical pesticide overuse. Yet, due to the distinctive attributes of the two types of pesticides, farmers often adopt a combination of both. This study aimed to probe the interdependent relationship underlying the mixed use of chemical pesticides and biopesticides by farmers in the rice–crayfish integrated system (RCIS) in Hubei province, China. We also sought to identify influencing factors and associated consequences of this practice. Given that the adoption of chemical pesticides and biopesticides by farmers is not mutually exclusive, a multivariable probit model was utilized to estimate simultaneous pesticide applications. Survey data from 736 RCIS farmers revealed that 10.50% of the sample farmers employ a combination of chemical pesticides and biopesticides. A substitution relationship was observed between the adoption of chemical pesticides and biopesticides by farmers, whereas no significant complementary relationship was found in the application of the two types of pesticides. The primary motivation for the mixed use of pesticides by farmers is to achieve superior pest control efficacy. Notably, when integrating the use of pesticides, farmers pay less attention to factors such as resource endowments and multiple production objectives. Further analysis indicated that farmers display significant concern for pesticide attributes including insecticidal efficacy, toxicity, insecticidal spectrum, and validity period. The mixed use of pesticides has resulted in a decreased frequency of pesticide application but has escalated the cost. While the mixed use of pesticides elevated the selling price of rice, no significant improvement was observed in yield and output value. The insights garnered from this study offer strategic implications for policymakers on how to enhance the judicious adoption of pesticides by farmers.

Reducing fertilizer use and increasing its efficiency will improve the quality of farmland and resource conservation. These are necessary steps to achieving green development in agriculture. Nevertheless, fertilizer-reduction and efficiency-increasing technologies (FREITs) remain limited. To improve the situation, 538 farmers in Jiangsu and Hubei Provinces were surveyed with the goal of measuring the information acquisition ability (IAA) of farmers using an Item Response Theory (IRT) model. A model of improved technology selection was employed in conjunction with an IV-probit model to examine the impacts of IAA on farmers’ adoption of FREITs. The results showed that 34.76% of the surveyed farmers had adopted FREITs, with 12.45% and 26.02% having adopted Soil Testing and Formula Fertilization Technology (STFFT) and Organic Fertilizer Replacement Technology (OFRT), respectively. Second, farmers who used more information access channels had greater IAA, which significantly improved their adoption of FREITs. Third, participation in technical training and an increased degree of technical understanding increased the probability of farmers adopting FREITs. The results remained robust after accounting for endogeneity and correlation. Consequently, enhancing farmers’ IAA, organizing technical training, and improving technical publicity will promote the adoption of FREITs.

Excessive fertilizer input and inefficient utilization in agricultural production have caused significant negative environmental impacts. Based on provincial panel data in China from 2005 to 2021, this study adopts the full-cost insurance pilot launched in 2018 and uses the DID method to empirically analyze its impact on fertilizer application intensity and utilization efficiency. The study reveals the following findings: (1) Implementing full-cost insurance can reduce fertilizer application intensity by 21.761% and increase utilization efficiency by 1.915%. (2) Full-cost insurance reduces fertilizer application intensity and improves fertilizer utilization efficiency by expanding the land scale and reducing the agricultural labor force. (3) Full-cost insurance significantly improves fertilizer utilization efficiency in high-risk and low-risk areas. Nevertheless, while the policy significantly reduces fertilizer application intensity in high-risk areas, its effect on low-risk areas is not apparent. (4) Full-cost insurance has an environmental protection effect. It can significantly reduce 11.593% of nitrogen pollution emissions, 2.577% of phosphorus pollution emissions, and 35.400% of equivalent pollution emissions. The implementation of full-cost insurance plays an important role in reducing fertilizer use and improving utilization efficiency. So, we should continue to intensify the promotion of full-cost insurance policy to fully leverage the advantages of agricultural insurance and promote sustainable agricultural development.

Enhancing farmers’ behaviors toward cultivated land quality protection is a crucial support in achieving sustainable agricultural development and the national food security strategy. This study aims to investigate the impact of land transfer-in on farmers’ behaviors regarding cultivated land quality protection, explore the underlying mechanisms, and analyze group heterogeneity. To achieve this, the study empirically estimates the impact of land transfer-in on farmers’ behaviors in protecting cultivated land quality using micro-survey data from 743 households in Hubei Province, while addressing endogeneity and conducting robustness checks. The study further explores the mechanisms and heterogeneity of the effects of land transfer-in on farmers’ cultivated land quality protection behaviors. The results reveal that (1) land transfer-in significantly increases the likelihood of farmers taking actual actions to protect cultivated land quality and enhances their awareness, thereby promoting protective behaviors; (2) land transfer-in facilitates these protective behaviors mainly through income incentives and social network interactions, while rental constraints may have a suppressive effect; (3) full-time farmers, those with higher agricultural literacy, those who access agricultural knowledge online, and those affected by natural disasters are more likely to engage in proactive land quality protection behaviors after land transfer-in.

Rice–crayfish coculture systems (RCSs) have been widely promoted in China as an efficient circular agriculture model that can simultaneously improve rice quality, raise the efficiency of utilization of resources, and increase farmers’ incomes. However, the herd behavior of farmers in the adoption of the rice–crayfish coculture system warrants more attention, as the rational adoption of this system by farmers is a prerequisite for achieving the above objectives. This paper analyses the formation mechanism of farmers’ herd behavior based on information cascade theory. Using micro-survey data from 603 farmers in China and a bivariate probit model, we examine the existence of herding effects in the adoption of RCSs by farmers and the inhibitory effect of information acquisition capability on herd behavior. To address possible endogeneity issues, we also conducted a robustness test using the IV-probit model. Furthermore, we tested for between-group differences in agricultural income between farmers with herding adoption and non-herding adoption. The study reveals that the larger the number of prior adopters, the higher the probability of blind adoption behavior by farmers, indicating the existence of a herd effect. Information acquisition ability could significantly inhibit the herd behavior of farmers in the adoption of RCSs. We also found that farmers’ herd behavior in the adoption of these systems was not economically rational. Based on the research findings, we proposed several constructive suggestions for policy perfection.

Promoting the transformation of green consumption has emerged as a critical pathway to address ecological constraints. However, existing research exhibits significant discrepancies in understanding the relationship between green attributes and purchase intention and lacks a deep unpacking of the underlying individual psychological mechanisms. Employing three situational experiments, this study integrates the chain effects of green attribute centrality (GAC), environmental concern (EC), and green trust (GT) to systematically explore the formation mechanism of consumers’ green purchase decisions. Results show three key findings: (1) When consumers exhibit high EC, GAC enhances their green purchase intention (GPI) more effectively; however, when EC is low, GAC demonstrates no significant differential impact on GPI. (2) The interaction between GAC and EC influences GPI via green perceived value (GPV) (i.e., this interaction effect is mediated by GPV). (3) GT further moderates these relationships: under high GT conditions, consumers with high EC show a stronger preference for high-centrality green products; conversely, under low GT conditions, such consumers exhibit a greater preference for low-centrality green products. This study provides a novel theoretical explanation and practical pathway for bridging the “attitude-behavior gap” in green consumption. It not only deepens the understanding of the mechanisms underlying green consumption decision-making but also offers precise references for enterprises to implement differentiated green marketing strategies and for policymakers to guide public green consumption.
