城镇化-自然生态系统协调发展水平及其对城乡收入差距的影响——基于长江上游成渝、黔中、滇中城市群的比较研究

Urbanization-Coordinated Development Level of Natural Ecology and Its Impact on Urban-Rural Income Gap:Based on the Perspective of a Comparative Study of Urban Agglomerations in Chengdu-Chongqing,Central Guizhou and Central Yunnan

党的十八大以来,绿色发展理念的提出对城乡收入差距形成的问题的思考提供了生态维度的思考路径。论文首先从理论模型角度分析了城镇化-自然生态系统协调发展对城乡收入差距的影响机制,并基于耦合协调模型测度了长江上游城市群城镇化-自然生态系统协调发展水平,进一步运用实证检验分析城镇化-自然生态系统协调发展水平对城乡收入差距的影响,研究结果表明:成渝城市群城镇化-自然生态系统协调发展水平处于相对较高水平,滇中、黔中城市群次之;成渝、黔中、滇中城市群中,城镇化-自然生态系统协调发展水平的提高,显著降低了城乡收入差距,但影响程度存在明显差异;并且通过运用变量替代和不同检验方法进行检验,其表明估计结果依然稳健。

Since the 18th National Congress of the Communist Party of China,the concept of green development has provided an ecological thinking path for the formation of urban-rural income gap.Based on this,this paper first analyzes the influence mechanism of urban-natural ecological coordinated development on urban-rural income gap from the perspective of theoretical model,and measures the coordinated development level of urban-rural ecologicalization in the upper reaches of the Yangtze River based on the coupled coordination model,and further analyzes the impact of the coordinated development level of urban-natural ecologicalization on the urban-rural income gap by empirical tests.The results show that the urbanization-natural ecological coordinated development level of Chengdu-Chongqing urban agglomeration is at a relatively high level,followed by urban agglomeration in central Guizhou,and urban agglomeration in central Yunnan.In the urban agglomerations,the raising of urbanization-natural ecological coordinated development level,significantly reduces the urban-rural income gap,but the degree of impact is significantly different,and by using variable substitution and different test methods to test,it shows that the estimated results are still stable.
