[Spatio-temporal Characteristics and Obstacle Factors of the Coupling Synergy Between New-type Urbanization and Low-carbonization of the Living Energy Consumption of Urban Residents].

Abstract

Clarifying the dynamics and mechanism of the coupling and coordination relationship between new-type urbanization and the low-carbonization of the living energy consumption of urban residents can provide basic data and theoretical support for the national low-carbon economy and other high-quality development strategies from the perspective of urbanization. The entropy method, coupling coordination model, kernel density estimation, and obstacle model were used to investigate the spatial and temporal characteristics, coupling coordination, and obstacle factors of the two systems of China's new-type urbanization and the low-carbonization of the living energy consumption of urban residents from 2005 to 2021. The results showed that： ① The overall level of new-type urbanization and low-carbonization of the living energy consumption of urban residents showed an upward trend, and both had obvious spatial differentiation characteristics. ② The coupling coordination degree of new-type urbanization and the low-carbonization of the living energy consumption of urban residents showed a clear upward trend, increasing from 0.553 in 2005 to 0.714 in 2021. The overall spatial pattern of the coupling coordination degree exhibited a strong positive correlation, spatial correlation was enhanced, local spatial structure and dependence of the direction of the fluctuation were weak, and certain path dependent characteristics were observed. ③ Economic urbanization was the dimension with the biggest obstacle in the guideline layer of the new-type urbanization system, with an average obstacle degree of 34.77%； the built-up area ratio was the indicator with the biggest obstacle degree in the system, with an average obstacle degree of 23.48%. In the system of low-carbonization of the living energy consumption of urban residents, the indicator of carbon emission per unit of energy consumption had the strongest barrier effect, with an average barrier degree of 29.13%, whereas the indicator of carbon emission density had the weakest barrier effect, with an average barrier degree of 3.34%. Therefore, each province is recommended to construct development plans according to local conditions, establish a cross-regional and multi-dimensional synergy and cooperation mechanism, and promote the construction of new-type urbanization in an orderly manner, to facilitate the realization of the "dual-carbon" goal.
