1990年以来浙江沿海各县市都获得了较快的发展,但区域发展差距也迅速扩大,沿海内部的区域差异成为浙江省区域差异的主要内容。运用锡尔系数分析1990年以来浙江沿海经济差异表明,浙江沿海总体经济差异呈先降低后上升的趋势,市内差异和市县间差异是总体差异的主要组成部分,而且市内差异不断扩大。影响区域差异的因子是多方面的,历史基础、中心城市规模、地理环境与自然资源、市场发育程度、全球化程度、信息化程度、区位和交通、人口数量与素质和区域发展策略等均对浙江沿海区域经济差异有不同程度的影响。通过多元回归分析各因素的影响程度,得出历史基础、市场发育程度、人口自然增长率、实际利用外资是浙江沿海经济差异的主要影响因素。

All the counties and cities in coastal area of Zhejiang have been increasing quickly since 1990, and at the same time, the regional economy exists disparity on growth rate, the relative rate of development, stages of development, and other aspects.The spatial structure of regional economy presents three core-peripheries.By Theil index, the regional economic disparity is analyzed in coastal area of Zhejiang since 1990, the trend of disparity is tending to be down and then rise, and the urban internal disparity and the disparity between city and county are the main components.Furthermore, the urban internal disparity continues to widen.The factors that impact on regional economic disparity are many-sided.Historical economic base, scale of central city, geographical environment and natural resources, level of market development, impact of globalization, informationization, location and transportation, quantity and quality of the population and regional development strategy are the factors which impact on regional economic disparity of coastal area of Zhejiang.Among all the factors, historical economic base, level of market development, actual utilization of foreign investment, natural population growth rate are the main factors to cause regional economic disparity of coastal area of Zhejiang by multiple regression analysis.
