Tax Burden and Influencing Factors During Waste Incineration Power PPP Project Operation

Abstract

Waste incineration power generation is an effective way to treat domestic waste as a resource, an effective way to reduce carbon emissions, and an important model for developing the circular economy, practicing the spirit of emission reduction promoted by COP26. The tax burden during operation of PPP (public-private partnerships) projects in this field directly affects the selection and development of the supply model. This paper selected the data of enterprises participating in the waste incineration power generation PPP project from the Ministry of Finance's PPP project management database and the financial data of the company from the CSMAR database for the corresponding year, and used tax burden evaluation indicators to empirically analyze the tax burden of the operation period of a waste incineration power generation PPP project from the perspectives of value-added tax and enterprise income tax. It was found that the asset-liability ratio, the income capacity from electricity sales, the profitability, and whether the preferential tax policy of "three exemptions and three halves" could significantly affect the corporate income tax burden of the project had to be considered. Combined with current preferential tax policies, this paper provided targeted optimization suggestions such as emphasizing the role of a "debt tax shield", optimizing the output structure, and extending the duration of the "three exemptions and three halves" tax incentives. The research in this paper is helpful to find an effective way to reduce the tax burden of enterprises, improve the economic benefits of waste incineration power generation projects, and also provide a reference for the government to formulate more reasonable tax policies and promote a better tax system.
