Cap-and-trade regulation provides incentives for manufacturers to reduce carbon emissions,but manufacturers’insufficient capital can disrupt the implementation of low-carbon emission reduction *** alleviate capital constraints,manufacturers can adopt external financing for low-carbon emission reduction *** paper studies the independent financing and financing cooperation behavior in a supply chain in which the manufacturer and retailer first implement low-carbon emission reduction technologies and then organize production and sales in accordance with wholesale price *** comparing the optimal profits and low-carbon emission reduction levels under the independent financing and financing cooperation mode,we come to the following conclusions:(1)Although financing interest increases the cost of the supply chain,manufacturers prefer to invest in reducing carbon emissions rather than buying carbon quotas.(2)When financing independently,a decentralized decision-making mode(MD)is the best choice for manufacturers.(3)In cooperative financing,when the supply chain adopts a decentralized decision-making mode(SD)in which the retailer determines the financing cost-sharing ratio according to their optimal profit,the profits of the supply chain and its members are significantly improved.(4)When manufacturers and retailers adopt a centralized decision-making model(SC)in cooperative financing,they jointly determine the financing cost-sharing ratio and the level of low-carbon emission *** the financing cost-sharing ratio meets a certain threshold range,the profits of manufacturers and retailers achieve Pareto improvement,indicating that this cooperative financing model is effective.

This study investigated the effect of credit constraints and credit unconstraints on the technical efficiency of hybrid maize growers in the Khyber Pakhtunkhwa Province(KPK) of Pakistan. The primary data were collected by a direct elicitation method from 510 maize growers of KPK Province. Stochastic frontier model techniques were used for technical efficiency analyses. The results revealed that the mean technical efficiency difference between the two groups was 10.2%. The results of technical inefficiency effect modeling demonstrated that education of the household head, family size, number of married family members, off-farm income, farming experience, tractor drill, water irrigation through a lined course, certified seed, extension services, household saving variables, and a credit size variable had positive effects on technical efficiency for both credit constrained farmers(CCFs) and credit unconstrained farmers(UCCFs). In addition, age of household head and fragmented land values had negative effects on technical efficiency for both groups. However, the interest rate had positive and negative impacts on the technical efficiency of CCFs and UCCFs, respectively. Our results have significant implications for policies related to land use, interest rate, and banking sector expansion in the rural areas of Pakistan.
