江苏省县域农村发展与城镇化耦合协调空间分异及调控机理

新型城镇化和乡村振兴两大国家战略有机结合是破解中国不平衡、不充分发展主要矛盾的重要前提，研究农村发展水平和城镇化水平的耦合协调程度可为城乡共治提供科学的决策依据。研究构建了农村发展与城镇化耦合发展理论框架，以江苏省为研究对象，借助耦合协调度模型分析了县域尺度农村发展与城镇化耦合协调空间分异特征，并针对两者耦合协调程度提出了相应调控策略。结果表明：(1)江苏省农村发展水平整体较高，空间格局大体上呈现由苏南向苏北逐渐降低的趋势。(2)县域之间城镇化水平差距较大，不均衡性较为明显。(3)绝大多数区县的农村发展与城镇化呈协调状态，仅有丰县和雎宁县呈轻度失调状态。(4)农村发展和城镇化耦合程度可划分为双滞后型、农村发展滞后型、城镇化滞后型和协调型4种类型，新时期应当因地制宜采取调控策略实现城乡协同治理。综上，江苏省农村发展水平和城镇化的耦合协调程度整体较好，但需要继续加强农村发展对城镇化的推动机制以及城镇化对农村发展的拉动机制，构成两者相互促进、相辅相成的良性循环系统。

Spatial Differentiation and Regulation Mechanism of Coupling Coordination Between Rural Development and Urbanization in County Region of Jiangsu Province

The organic combination of the two national strategies of new urbanization and rural revitalization is an important prerequisite for addressing the major contradiction in unbalanced and inadequate development in China. Studying the degree of coupling and coordination between the level of rural development and the level of urbanization can provide a scientific decision-making basis for urban-rural co-governance. The theoretical framework for the coupling development of rural development and urbanization was constructed. Taking Jiangsu Province as the research object, we analyzed the spatial differentiation characteristics of the coupling and coordination between rural development and urbanization at the county level by means of a coupling model of coordination, and put forward corresponding control strategies for the coupling and coordination degree between rural development and urbanization. The results show that:(1)the overall level of rural development in Jiangsu Province is relatively high, and the spatial pattern is generally shows a trend of gradually decreasing from south to north;(2)there is a large gap in the level of urbanization between counties, and the imbalance is obvious;(3)except for Fengxian County and Suining County, which are slightly out of balance, rural development and urbanization in most districts and counties are in a state of coordination;(4)the degree of coupling between rural development and urbanization can be divided into four types including double-lag type(namely lagging both in rural development and urbanization), lagging in rural development, lagging in urbanization, and coordination type; in the new era, adjustment strategies should be adopted according to local conditions to achieve coordinated urban-rural co-governance. The level of coupling coordination between rural development and urbanization in Jiangsu Province is generally good, but it is necessary to continue to strengthen the promotion mechanism of rural development to urbanization and the pulling mechanism of urbanization to rural development, forming a virtuous cycle system that promotes and complements each other.
