Market Structure And Carbon Emission Intensity Of Enterprises

Improving the carbon emission efficiency of enterprises and reducing the carbon emission intensity of enterprises are of great significance for achieving the strategic goal of "carbon peak,carbon neutral".In the early stage,carbon emission reduction was mainly through administrative means including energy quotas and resource taxes,ignoring the important role of market structure.In fact,there is a very important relationship between the market structure and the carbon emissions of enterprises.A reasonable market structure can effectively promote the efficiency of enterprise resource allocation and strengthen the willingness of enterprises to innovate.Therefore,building a reasonable market structure is of great significance to achieve the goal of "double carbon".This paper first combs the domestic and foreign literature related to market structure and carbon emission intensity,and theoretically analyzes the relationship between market structure and enterprise carbon emissions and the internal mechanism.Secondly,taking China’s industrial enterprises from 2008 to 2014 as the research object,using the fixed effect model and the intermediary effect model,this paper empirically analyzes the relationship between the market structure and the carbon emission intensity of enterprises.The research results show that:(1)there is an obvious negative correlation between the market structure measured by market concentration and the carbon emission intensity of enterprises.The higher the market concentration,the lower the carbon emission intensity of enterprises;Adding the quadratic and cubic terms of market concentration shows that there is no nonlinear relationship between market institutions and the carbon emission intensity of enterprises.(2)The influence of market structure on the carbon emission intensity of enterprises is heterogeneous.For non-state-owned enterprises,enterprises in high-energy consumption industries,and enterprises in low-market areas,the increase of market concentration has significantly reduced the carbon emission intensity of enterprises,while for state-owned enterprises,enterprises in low-energy consumption industries,and enterprises in high-market areas,the increase of market concentration has no significant impact on the carbon emission intensity of enterprises.(3)The intensity of government environmental regulation has a positive regulatory effect on the impact of market structure on the carbon emission intensity of enterprises.The higher the intensity of government environmental regulation,the stronger the emission reduction effect of market concentration.(4)The mechanism analysis shows that the efficiency of enterprise resource allocation,enterprise technological innovation and enterprise energy consumption structure all have partial intermediary effects,that is,the increase of market concentration can reduce the intensity of enterprise carbon emissions by improving the efficiency of enterprise resource allocation,improving the level of enterprise technological innovation and optimizing enterprise energy consumption structure.Based on the above analysis,the proposed measures mainly include:(1)to improve market concentration and optimize market structure.(2)Deepen the reform of state-owned enterprises and stimulate the vitality of state-owned enterprises.(3)We will deepen market-oriented reform and improve the level of marketization.(4)We should improve government environmental regulations and better play the role of regulation,supervision and guidance.
