To achieve carbon peak by 2030 and carbon neutrality by 2060 is a major strategic deployment of the central government and China's solemn commitment to the world's response to climate change. In order to achieve the goal of double carbon, China's factor resource allocation needs to consider the constraints of carbon emissions. In China's special institutional context, land is an important policy tool for central and local governments to promote economic development. However, government-led land allocation is prone to resource misallocation, such as land misallocation to low-end enterprises with high energy consumption and high emissions, which will lead to high carbon emissions and loss of production efficiency. In order to achieve the goal of double carbon in China's development, reducing the mismatch of land resources is an important way, and it is also a problem concerned by the academic circle. In the new form, how to properly use land policy tools to achieve the goal of dual carbon in development, we need to answer the following questions: To what extent is the misallocation of urban land resources in China constrained by carbon emissions? How to measure? What are the effects and mechanisms of carbon emissions in mismatched cities with land resources? How to achieve the goal of reducing carbon emissions by improving the mismatch of urban land resources? What can we learn from previous policy practices? These issues have not been discussed in depth in the previous literature. Therefore, this study calculates the misallocation of urban land resources in China considering carbon emissions. Secondly, based on the calculation data of land resource mismatch, the impact of urban land resource mismatch on carbon emissions is demonstrated. Thirdly, the low-carbon city pilot was used to demonstrate the impact mechanism of urban land resources mismatch on carbon emissions. Finally, the governance policy of land resource mismatch based on the dual carbon goal is studied, in order to provide policy support for China to achieve the dual carbon goal in high-quality development.
The innovation of this subject. This paper considers carbon emission constraint and expands the measurement method of land resource mismatch. Through theoretical and empirical analysis, it is proved that land is an important policy tool to achieve the goal of double carbon in China's development. Progressive DID was used to study the impact of low-carbon city pilot impact on carbon emissions through land allocation, and to enrich the empirical research on carbon reduction policy evaluation in China.
