Research On The Impact Of Environmental Regulation On Low-carbon Utilization Of Urban Land

General Secretary Xi Jinping proposed the goals of “2030 carbon peak and 2060 carbon neutrality” as a strategic choice to comply with the comprehensive green and low-carbon transformation of society and achieve high-quality urban development.As a necessary resource and basic carrier for urban production and construction activities,the low-carbon utilization of urban land is an important anchor point for government policy formulation and related system optimization.Although governments at all levels have issued a variety of incentives and penalties for environmental regulations to improve the low-carbon utilization of urban land,under the current constraints of local government competition,it is often difficult to achieve the expected results of environmental regulation enforcement,and it adversely affects the process of promoting the decarbonization of urban land use.This study firstly summarizes the research progress about the low-carbon utilization of urban land,the relationship between environmental regulation and low-carbon utilization of urban land,and the relationship between local government competition and environmental regulation.Second,defining the core concepts of “environmental regulation”,“urban land low-carbon utilization”,and “local government competition”,the government competition theory,externality theory and sustainable land use theory are explained in detail.Again,the environmental regulation intensity and the low-carbon urban land use levels are measured separately,and analyze their time-series evolution characteristics and spatial distributions.Finally,using the systematic generalized moments estimation method,the panel data of 26 prefecture-level cities in the Yangtze River Delta city cluster from 2005-2020 are used as the study sample,dynamic panel models of the impact of environmental regulation on low-carbon urban land utilization and the impact of local government competition regulates the relationship between environmental regulation and urban land low-carbon utilization are constructed for empirical analysis,and its validity and robustness are tested.The research results show that:(1)The overall environmental regulation intensity of the Yangtze River Delta urban agglomeration showed a tortuous upward trend,with obvious spatial differences,and the high-intensity area gradually shifted from the southern cities of the Yangtze River Delta to the eastern and northern cities.(2)The low-carbon utilization level of urban land in the Yangtze River Delta urban agglomeration has increased year by year,and there are structural characteristics of diffusion from the higher level area in the east to the lower level area in the west in the geographical spatial distribution,and there is an inertial influence on the low-carbon utilization of urban land in the previous period.(3)Environmental regulation has a catalytic effect on improving the low-carbon utilization of urban land,which is conducive to achieving a win-win situation for both economic and green benefits.(4)Local government competition plays a negative regulatory role in the relationship between environmental regulation and urban land low-carbon utilization.Local government officials,faced with conflicting pressures on performance and environmental protection,are more likely to adopt competing government policies that prioritize performance,and creates a relaxed environmental regulatory atmosphere for rapid economic development,leading to a decline in the level of low-carbon urban land utilization.Therefore,the environmental regulation system should be further improved,the performance appraisal system of local government officials should be optimized,with high-quality development as the guide,technological innovation and achievement transformation of land subjects should be encouraged to improve the level of urban land low-carbon utilization.
