长江三角洲对外开放的区域差异及成因分析

Foreign Openness of Yangtze River Delta: Regional Difference and Causes

选择出口依存度和资本依存度2个指标构建对外开放度指数,对长江三角洲15个城市的对外开放度进行测算。结果表明,长江三角洲各市的对外开放度差异很大,可以划分为3个层次:高开放度城市(苏州、上海、宁波、无锡)、中等开放度城市(嘉兴、杭州、绍兴、南京、常州、南通)和低开放度城市(舟山、湖州、镇江、扬州、泰州)。造成长江三角洲对外开放度空间差异的主要因素是区位条件、经济基础和政策因素等。

Selecting depending degree of export and depending degree of foreign direct investment to form foreign openness rate, this paper measures the foreign openness rate of 15 cities in Yangtze River Delta. It is indicated that foreign openness rate of 15 cities varies distinctly and may be classified into 3 types： higher openness rate cities （Suzhou, Shanghai, Ningbo, Wuxi）, middle open- ness rate cities （Jiaxing, Hangzhou, Shaoxing, Nanjing, Changzhou, Nantong） and lower openness rate cities （Zhoushan, Huzhou, Zhengjiang, Yangzhou, Taizhou）. Affecting factors of foreign openness rate are mainly location, economy and policy.
