This paper investigates the emission reduction performance for supply chain members in both single-channel and exclusive dual-channel cases. Two game scenarios (Manufacturer Stackelberg and Retailer Stackelberg) are examined under different channel structures. Furthermore, we introduce government subsidies as an impact factor of low-carbon strategy adoption. In the single-channel (Case 1), we mainly examine the influence of consumers’ price-sensitivity on channel members’ optimal decisions. In the dual-channel (Case 2), we focus on the joint impact of product substitutability and different channel power structures on the optimal decisions under asymmetric related channel status. The analysis suggests that the Stackelberg leaders always perform better than their corresponding followers before emission reduction, while they may not necessarily yield more benefits after emission reduction. The implementation of low-carbon strategy depends on parameters like product substitutability and channel base demand. Finally, all the supply chain members will encounter a Prisoner’s Dilemma when the product substitutability is relatively high.

The development of online shopping carnivals (OSCs) is in full bloom due to the support of logistics industry and information technology. More and more people are keen to participate in them. This study contributes to literature by exploring the role of motivational factors (based on utilitarian and hedonic shopping values dimension) of the intention to participate in the actual purchase behavior of consumers and their shopping well-being in OSC. A model is developed and tested to explain consumers’ shopping process in the context of OSC. Results show that hedonic shopping values are primarily influenced by entertainment construct, and utilitarian shopping values are positively related to monetary saving, selection, and convenience. Furthermore, the correlation between hedonic shopping value and intention to participate is higher than that between utilitarian shopping value and intention to participate. The findings indicate that intention to participate in OSC exerts a stronger influence on shopping well-being than the effect on actual purchases.
