中国省域数字-能源-经济-环境耦合协调的时空特征

Spatial and Temporal Characteristics of Digital-energy-economy-environment Coupling Coordination in China

数字技术的广泛应用是推动经济高质量发展的必由之路。基于数字、能源、经济与环境融合的理论分析,通过修正的耦合协调度模型测算中国30个省份(因数据缺失,未包括西藏和港澳台地区)2012—2021年四个领域的融合水平,并采用空间自相关模型对其空间分布特征进行研究。结果表明,全国数字、能源、经济与环境的耦合水平在观测期内呈良好上升趋势,最终处于基本协调状态;东中西部地区融合发展步调较为同步,但省域间协调状态等级分级明显,且部分地域间具有明显的空间集聚效应。

The wide application of digital technology is the only way to promote high-quality economic development.Based on the theoretical analysis of the integration of digital,energy,economy and environment,the integration level of four fields in 30 provinces(due to the lack of data,the statistical data mentioned here do not include the Tibet Autonomous Region,the Hong Kong Special Administrative Region,the Macao Special Administrative Region and Taiwan Province)in China from 2012 to 2021 was estimated by the modified coupling coordination degree model,and the spatial autocorrelation model was used to study their spatial distribution characteristics.The results show that the coupling levels of national digital,energy,economy and environment show a good upward trend during the observation period,and finally are in a basic coordination state.The pace of integration and development in the eastern and western regions is relatively synchronous,but the level of coordination among provinces is obvious,and some regions have obvious spatial agglomeration effect.
