长江经济带旅游产业与城市人居环境协调效应及互动响应

Coordination Effect and Interactive Response Between the Tourism Industry and Urban Human Settlement Environment Along Yangtze River Economic Belt

作为我国大河流域综合治理发展的关键一环,探究长江经济带旅游产业与城市人居环境协调关系对实现两系统可持续发展有重大意义。以长江经济带108地级市为研究对象,通过构建旅游产业与城市人居环境耦合协调指标体系,从地理时空二维角度评价其耦合协调演化趋势,并结合PVAR模型探究两系统之间的互动响应关系,主要结论如下:(1)长江经济带各地级市两系统的评价指数空间非均衡现象显著,高评价指数地区呈集聚态势分布,且集中于各区域核心城市,低评价指数地区呈分散态势分布,广泛分布于中西部地区。(2)耦合协调度呈逐步上升态势,总体耦合协调类型为低度耦合协调过渡到中度耦合协调,三大地区差异逐渐缩小,长江经济带总体呈均衡化、健康化发展态势。(3)两系统存在长期均衡关系,互为格兰杰原因。二者之间对自身和对方都存在相互影响的关系,相互之间形成正向累进效应,并且城市人居环境对旅游产业的促进程度要比旅游产业对城市人居环境的提升作用更大。据此提出治理建议,以期为长江经济带旅游产业与城市人居环境可持续发展建言献策。

As a key link in the comprehensive governance and development of China’s major river basins,it is of great significance to explore the coordination between tourism industry and urban human settlement environment in the Yangtze River Economic Belt for the sustainable development of the two systems.By investigating 108 prefectural-level cities along the Yangtze River Economic Belt,this paper constructs the coupling coordination index system between the tourism industry and urban human settlement environment,evaluating the evolution trends of its coupling coordination from the two perspectives of geography and time-interspace,and exploring the interactive responsive relationship between the two systems using PVAR model,the essay reaches three main conclusions as below:(1) The evaluation indexes of tourism industry and urban human settlement environment in prefecture-level cities of the Yangtze Economic Belt show significant spatial disequilibrium.High-evaluation regions tend to be distributed in an agglomeration trend and focus on core cities within each region while low-evaluation regions tend to be distributed in a decentralization trend and focus on the middle west area.(2) The degree of coupling coordination gradually increases,and the overall type of coupling coordination is from low coupling coordination to moderate coupling coordination.The differences among the three regions are gradually narrowing,and the Yangtze River Economic Belt is developing in a balanced and healthy way on the whole.(3) There is a long-term equilibrium relationship between the two systems,which is granger cause for each other.The two have mutual influence on themselves and each other,forming a positive progressive effect between them,and the promotion degree of urban human settlement environment to the tourism industry is greater than that of the tourism industry to improve the urban human settlement environment.Based on the above research results,governance suggestions are put forward in order to provide ideas for the sustainable development of tourism industry and urban human settlement environment in the Yangtze River Economic Belt.
