Online channel selection within a capital-constrained green supply chain under government subsidies
摘要
Government subsidies are effective policies to promote sustainable development, and are crucial to businesses' green initiatives. This paper studies two kinds of subsidy policies: green R&D and production cost subsidy. Financial constraints and government subsidy policies are important factors affecting supply chain members' green technology innovation and online channel decisions. Therefore, a Stackelberg model is proposed to analyze how the manufacturer and platform make online channel decisions under different government subsidies. The research finds that, first of all, although the two subsidy policies help supply chain participants increase their earnings, there are differences in their impact on decision-making. Wholesale and retail prices fall with the production cost subsidies and rise with the green R&D subsidies. When the production costs are low, green R&D subsidies are more conducive to improving the products greenness and reducing product prices. Otherwise, production cost subsidies are more advantageous in terms of greenness and price. Second, decisions such as product greenness and price are closely tied to the interest rates in manufacturers' bank financing, and production costs play a key role. When the production cost is high, the product price and greenness will increase with interest rates rising, and decrease when the production cost is low. Third, higher interest rates reduce profits but do not affect sales patterns, and subsidies can boost profits. Under certain conditions, the effect of subsidy policies on greenness and prices is opposite to that of interest rates, which can offset some of the impact of rising interest rates.
