Impact Mechanism of China's Smart City Construction on Carbon Emission Efficiency
Focusing on the perspective of digital ecology,this paper uses network analysis and exponential random graph model to take into account the overall and individual effects and explores the impact mechanism of China's smart city construction on carbon emission efficiency from the perspectives of relevance,dynamics and ag-gregation.The results show that:(1)From the perspective of the overall network and individual network,the con-struction of smart city significantly improves the index performance of the carbon emission efficiency network,pro-motes the cooperation between cities,and ensures the rational allocation and utilization of resources.Developed and resource-based cities occupy a dominant position in the network and have greater control capabilities.(2)From the perspective of network topology,the scale-free nature and small-world nature are not significant,while the number of core cities in the southeast coastal area and North China gradually increases,and with the gradual maturity of smart city construction,the local agglomeration is significantly strengthened.(3)From the perspective of influen-cing factors,reciprocity has a positive correlation with the network,the impact of smart talents on the network is the most significant,and the development of smart environment,smart economy and smart technology has an improve-ment effect on carbon emission efficiency,but there are periodic changes,and the impact on carbon emission effi-ciency is not regular.
