中国“无废城市”发展水平的空间关联结构与影响机制

Spatial Correlation Structure and Influencing Mechanism of Development Level of Zerowaste Cities in China

基于熵权TOPSIS法测度2004~2021年中国“无废城市”发展水平,采用社会网络分析法和空间杜宾模型探究“无废城市”发展水平的空间关联网络结构与影响机制.结果表明:①“无废城市”发展水平在全国、东部和中部总体呈下降趋势,在西部总体呈上升趋势;②“无废城市”发展水平的空间关联呈现核心-边缘结构,网络密度总体呈上升趋势,网络整体趋于稳定状态;③北京、上海、江苏、浙江、福建和广东处于网络的中心和主导位置;④北京、天津、上海和江苏属于“净受益”板块,浙江、福建和广东属于“经纪人”板块,其余省份属于“净溢出”板块;⑤城镇化水平、经济发展水平、技术创新水平、外商投资水平、环境规制、政府干预和人口规模分别对本地或邻近省份“无废城市”发展水平产生显著影响.研究结果可为各地区“无废城市”建设与协同发展政策的提出提供借鉴.

Based on the entropy weight TOPSIS method to measure the development level of“zero-waste cities”in China from 2004 to 2021,the social network analysis method and spatial Durbin model were used to explore the spatial correlation network structure and impact mechanism of the development level of“zero-waste cities.”The results showed that:①The development level of“zero-waste cities”was generally on the decline in the whole country and the eastern and central regions.However,it was on the rise in the western regions.②The spatial correlation of the development level of“zero-waste cities”presented a core-edge structure,with an overall upward trend in network density and a stable state in the overall network.③Beijing,Shanghai,Jiangsu,Zhejiang,Fujian,and Guangdong were at the center and dominant position of the network.④Beijing,Tianjin,Shanghai,and Jiangsu belonged to the“net benefit”sector;Zhejiang,Fujian,and Guangdong belonged to the“broker”sector;and the other provinces belonged to the“net overflow”sectors.⑤The level of urbanization,economic development,technological innovation,foreign investment,environmental regulations,government intervention,and population size had a significant impact on the development level of“zero-waste cities”in local or neighboring provinces,respectively.The research results can provide a reference for the proposal of policies for constructing and coordinating the development of“zero-waste cities”in various regions.
