长三角地区城乡耦合协调发展差异性研究

Research on the Differences of Urban-Rural Coordinated Development in Yangtze River Delta

以长三角地区16个城市为例,引入耦合度函数与耦合协调度函数构建城乡系统耦合模型,选取耦合测度指标体系,对长三角2003-2011年城乡系统耦合协调性进行测度,深入分析其城乡系统之间相互依赖、相互协调、相互促进的动态演化过程。结果表明,城乡耦合协调度与地区经济发展水平呈现明显的正相关;从耦合协调度来看,上海最高,浙江的杭州、宁波、嘉兴、绍兴和台州以及江苏的南京、苏州、无锡、南通和常州次之,浙江的湖州和舟山以及江苏的泰州、镇江和扬州最差;从耦合协调类型来看,上海、南京和镇江的耦合协调类型基本表现为乡村发展滞后型;苏州、杭州、无锡、常州和湖州的耦合协调类型基本表现为城乡同步发展型;宁波、嘉兴、绍兴、台州、南通、泰州、扬州和舟山基本表现为乡村发展超前型。

Taking 16 cities in Yangtze River Delta region as examples,the coupling degree function and coupling coordination degree function was introduced. By constructing the evaluation index system for the coupling coordination correlation, the de-gree of coupling coordination development between urban and rural areas in Yangtze River Delta region in the period of 2003-2011 was estimated.The dynamic evolution which was mutually dependent ,mutually accommodating and mutually pro-moted in urban-rural system was analyzed. And it is showed that there was an obviously positive correlation between the de-gree of urban-rural coupling coordination and the level of regional economic development. From the degree of coupling coor-dination, Shanghai had the highest coupling co-ordination degree, Hangzhou, Ningbo, Jiaxing, Shaoxing, Taizhou in Zhe-jiang Province and Nanjing, Suzhou, Wuxi, Nantong, Changzhou in Jiangsu province took the second place, Huzhou, Zhoushan in Zhejiang province and Taizhou, Zhenjiang and Yangzhou had the lowest degree.From the type of coupling coor-dination, Shanghai and Nanjing, Zhenjiang were the retarded type of rural development, Suzhou, Hangzhou, Wuxi, Changzhou and Huzhou were the synchronous type. Meanwhile, Ningbo, Jianxing, Shaoxing, Taizhou, Nantong, Taizhou, Yangzhou and Zhoushan were the advanced type.
