To ensure a reliable electricity supply, more governments implement subsidy policies to promote the adoption of innovative technologies by renewable energy producers to enhance supply reliability. We compare two types of subsidies provided by a government: investment subsidy (IS) policy, which is implemented in the deployment stage to directly reduce improvement costs, and operational subsidy (OS) policy, which is implemented in the operational stage to increase the renewable energy producer’s marginal returns. First, we show that without government intervention, customers’ low green consciousness or higher improvement costs may prevent the renewable energy producer from enhancing supply reliability. Second, through a comprehensive comparison, we find that both subsidy policies can incentivize the renewable energy producer to improve supply reliability when customers are more green-conscious, and the improvement cost is high. However, the OS policy and the IS policy operate on different mechanisms: the IS policy can directly alleviate the improvement cost burden on the renewable energy producer, while the OS policy serves a dual role of increasing the renewable energy producer’s marginal operational profit and expanding the market demand for renewable electricity. When customers’ green consciousness is low, the government can only choose whether or not to implement the OS policy. Finally, we highlight that the implementation of the IS policy by the government may not be more beneficial to both the renewable energy producer and customers compared to the OS policy. This result informs regulators that energy security should be considered when designing subsidy policies and should not be limited to promoting the interests of participants.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"139 ","pages":"Article 107926"},"PeriodicalIF":13.6,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142420847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a theoretical four-way game model to explore the impact of corporate pollution transfer, considering environmental regulation by the central government and third-party oversight, as well as collusion between local governments and firms. Using data from China's A-share listed companies from 2007 to 2021, this study examines whether polluting firms engage in pollution transfer in response to environmental policies, with the Low-carbon City Pilot Policy (LCPP) serving as a proxy for government environmental signals. The findings reveal that the LCPP generally affects corporate pollution transfer. Mechanism analysis shows that the LCPP reduces pollution transfer through both formal and informal regulatory channels. Heterogeneity analysis further indicates that the pollution transfer effect is more pronounced in local state-owned enterprises, companies with a history of financial fraud, and highly polluting industries. Additionally, the study highlights that collusion between the government and enterprises promotes corporate pollution transfer, while changes in local government personnel disrupt this collusion and reduce pollution transfer. The research also identifies the supply chain as a key transmission path for pollution transfer. This work not only advances theoretical and empirical understanding of corporate behavior under environmental policy influence but also enriches research on government-enterprise relations and the effectiveness of environmental policies. It offers theoretical support and policy recommendations for constructing a rational green economic development system in China.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"139 ","pages":"Article 107935"},"PeriodicalIF":13.6,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142326716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the degree of marketization exceeds 9.280, the influence of political connections on investment efficiency is statistically insignificant. At a low marketization stage, political connections enhance the ability of enterprises to acquire resources through four kinds of external financing channels: bank credit, corporate bonds, commercial credit, and equity financing.
