1 Matching-game approach for green technology investment strategies in a supply chain under environmental regulations
رویکرد بازی تطبیقی برای استراتژی های سرمایه گذاری فناوری سبز در یک زنجیره تأمین تحت مقررات زیست محیطی-2021
Facing increasingly severe environmental problems, green technology (GT) innovation has become an effective way to achieve the sustainable development of firms. Many manufacturers often choose and invest in appropriate GTs from GT-suppliers to improve the environmental impact of production. But others abandon GTs because they are too expensive to invest in. This paper thereby studies the dynamic investment strategy of GT in a manufacturer-supplier supply chain and explores the optimal government subsidy incentive and its impact on investment and sustainable production decisions. Firstly, an original two-sided matching game model (including two-sided matching analysis and Nash equilibrium analysis) is presented to study the matching process between a manufacturer with a limited investment budget and a GT-supplier with GTs and to determine the optimal GT investment-production strategy. Then, a government-manufacturer Stackelberg game model integrating differential game is constructed to determine the optimal government subsidy strategy and to investigate the effect of government subsidy on investment-production decisions. The results show that stable matching between the manufacturer and GT-supplier can be obtained. Numerical simulations verify the feasibility and rationality of the proposed matching game mechanism and demonstrate that GT investment profit is higher than non-investment profit, and subsidy profit is better than non-subsidy profit. The increase in the carbon price leads to an increase in the GT investment intensity. The increase in the carbon price can cause an increase in product greenness and green demand. The contributions of this paper are in providing an infrastructure for studying how managers can obtain the optimal GT investment-production strategy in the supply chain, and how the government formulates the optimal subsidy strategy to stimulate managers’ GT innovation behavior.

2 Supply chain coordination with green technology under cap-and-trade regulation
هماهنگی زنجیره تامین با تکنولوژی سبز تحت مقررات معامله و تجارت-2017
Cap-and-trade regulation is generally accepted as one of the most effective market-based mechanisms to curb carbon emissions. In this paper, we study the production and emission abatement decisions of a Make-To-Order supply chain consisting of a manufacturer and a retailer under cap-and trade regulation. Specifically, the manufacturer can reduce unit product carbon emission by using green technology, with the cooperation of a retailer by certain contracts, who sell the products to environment-concerned consumers. Wholesale price and cost sharing contracts are considered in the supply chain. We list some main conclusions here. First, as carbon trading price increases, the optimal production quantities (the optimal abatement levels) firstly decrease (increase) and then remain constant. Second, both wholesale price and cost sharing contracts can coordinate the supply chain. Last, combining the optimal operational decisions under the two contracts with two-part tariff agreement, we design a contract in which the retailer pays a lump fee to the manufacturer, and find that there is an interval of the lump fee to achieve Pareto improvement for the two firms.
