Abstract

China has been implementing huge scale of urbanization in the past several decades and this will continue in the coming future years. Whilst the urbanization growth has presented good benefits to social and economic development in China, it has also brought severe challenges to the resource environment carrying capacity, such as air pollution, overloaded land resources. These challenges present differently in different provinces, which leads to the disparity in development between provinces. There has been growing concern whether the urbanization growth in different provinces is coordinated with resource environment carrying capacity (RECC), but this question has not been addressed in previous studies. This paper presents a critical analysis on the coordination between urbanization growth and resources environment carrying capacity (RECC) from provincial perspective in the context of China. A measurement of coordination degree (CD) is used to measure whether and to what extent that urbanization growth and RECC are coordinated by applying coupling coordination degree model (CCDM). The research data are collected from 30 provinces in China. The results suggest that the average coordination performance among the provinces experienced a steady growth during the period of 2005-2016, but there still exists big room for improvement towards well balanced coordination performance. From provincial perspective, the good performers are mainly economically developed provinces. The findings provide valuable references for the governments at both central and local level to adopt proper policy measures where necessary to improvement the coordination performance between urbanization and RECC.

摘要

中国在过去几十年中一直在实施大规模的城市化,未来几年还将继续推进。城市化的发展给中国的社会和经济发展带来了好处,但也给资源环境承载能力带来了严峻挑战,如空气污染、土地资源超载等。这些挑战在不同省份表现不同,导致了省份之间发展的差异。人们越来越关注不同省份的城市化增长是否与资源环境承载能力(RECC)相协调,但这一问题在以前的研究中并未得到解决。本文从省级视角出发,对中国城市化增长与资源环境承载能力(RECC)之间的协调性进行了深入分析。本文采用耦合协调度模型(CCDM),通过协调度(CD)的测量来衡量城市化增长与 RECC 之间的协调程度和协调程度。研究数据来自中国 30 个省份。结果表明,2005-2016 年期间,各省之间的协调绩效平均呈稳步增长趋势,但要实现均衡协调绩效仍有很大的提升空间。从省级角度来看,表现较好的主要是经济发达的省份。这些发现为中央和地方政府提供了有价值的参考,以便在必要时采取适当的政策措施,提高城市化和 RECC 之间的协调绩效。
