Abstract:Focusing on a secondary supply chain consisting of a manufacturer and retailer investing in low-carbon emission reduction technology, the impact of different subsidy strategies on supply chain decision-making was explored. Through numerical simulation, it is found that the low-carbon emission reduction, manufacturer and retailer profits under the government subsidy low-carbon product consumer strategy are higher than other subsidy strategies. However, this subsidy strategy is more suitable for the early stage of low-carbon emission reduction products entering the market, as it is conducive to the market development of low-carbon emission reduction products. In the long run, the performance price ratio of the evaluation index system under the government subsidy strategy for low-carbon emission reduction technology is the highest, which can more effectively promote enterprises to invest in low-carbon emission reduction technology.
