Abstract: As environmental pollution issues become increasingly severe, the comprehensive green transformation of the manufacturing industry has emerged as an urgent and important topic. However, the characteristics of high investment, high risk, long cycles, and slow effects, combined with many companies’ pursuit of short-term benefits, result in a lack of motivation and willingness to implement green transformation. In this context, the government, as the regulatory body for the green transformation of manufacturing enterprises, needs to take certain incentive measures to reduce the cost pressure of green transformation for manufacturing enterprises, thereby promoting their implementation of green transformation. However, from a long-term perspective, excessive government subsidies not only increase the fiscal burden of local governments but also suppress the innovation ability of enterprises. Therefore, in promoting the green transformation of the manufacturing industry, it is important to find a balance point that considers both the government’s fiscal capacity and stimulates the long-term transformation motivation of enterprises. Therefore, designing a reasonable government subsidy mechanism that can effectively stimulate manufacturing enterprises’ motivation and willingness for green transformation, while avoiding significant financial pressure on local governments, is the key to achieving a comprehensive green transformation of the manufacturing industry.
   This paper first builds an improved Rank-Dependent Expected Utility (RDEU) model based on the RDEU theory and evolutionary game theory, considering the impact of government subsidies and transformation costs on the emotions of local governments and manufacturing enterprises. Secondly, it solves and analyzes the evolutionary stability of game strategies of local governments and manufacturing enterprises under different emotional combinations, thereby revealing the possible changes in their decision-making behaviors of governments and manufacturing enterprises under different emotional combinations of states. Finally, the above results are analyzed through numerical simulation, and the sensitivity analysis of the amount of government subsidy and transformation cost in the scenario of pessimistic local government and optimistic manufacturing enterprises is conducted to further explore the impact of government subsidy and enterprise transformation cost on decision-making.
   The research finds: (1) When local governments are in a rational state, there is a natural contradiction between socio-economic growth and environmental protection in their view, leading to a rational choice by local governments not to prioritize “efforts for environmental protection”. This choice does not promote the green transformation of manufacturing and is detrimental to sustainable development of society. (2) When local governments are influenced by emotions, if the government subsidy is low, although the government may have an optimistic attitude towards implementing subsidy policies. However, such a low subsidy policy is unlikely to motivate manufacturing enterprises to choose green transformation, which is still disadvantageous to the sustainable development of society. (3) Only when local governments show pessimistic emotions, and manufacturing enterprises are in a rational state or optimistic emotions, can this promote local governments to implement subsidy policies and manufacturing enterprises to choose comprehensive green transformation, which will benefit the sustainable development of society. (4) For manufacturing enterprises with different transformation costs, there are different optimal subsidy intervals. (5) Enterprises with lower transformation costs are more likely to exhibit shortsighted behavior, caring more about the benefits they can obtain from government subsidies. In contrast, those with higher transformation costs are often less sensitive to the amount of government subsidies.
   Based on these findings, this study provides decision-making recommendations for governments and manufacturing enterprises, aimed at helping achieve the comprehensive green transformation of the manufacturing industry, thereby promoting the sustainable development of society.
