区域经济空间分异及其演变分析研究——以浙江省为例

区域经济空间分异是伴随区域经济增长而产生的,是区域经济空间结构研究中的重要内容之一。在理论研究的基础上分析了区域经济空间分异产生的原因是受到区域空间结构的影响,总结了区域经济空间分异的现象表征主要体现在绝对差异、相对差异和经济重心3个方面,并对这3个方面的测度方法进行了研究总结,构建了区域经济空间分异的测度体系。在此基础上,以浙江省作为实证研究对象,以各县域GDP为经济发展水平的衡量指标,综合运用数理统计方法和GIS方法,对1988~2008年浙江省区域经济空间分异的情况做了定量分析。实证研究结果表明浙江省区域经济差距呈现台阶式扩大,主要由富裕地区引起,并且经济重心在不断转移。结果与1988~2008年浙江省的实际发展情况较为吻合,表明该测度分析体系具有一定的科学合理,在未来类似研究中值得继续推广。

RESEARCH ON SPATIAL VARIATION AND EVOLUTION OF REGIONAL ECONOMY——A CASE STUDY OF ZHEJIANG PROVINCE

Accompanied by regional economic growth,regional economic spatial variation has so far become an important part of studies upon regional economic spatial structures.Based on the study of the theory,the paper points out that the reason of regional economy spatial variation is regional spatial structure and the phenomenon characterization of regional economy spatial variation reflect in three aspects:absolute difference,relative difference and economic gravity centre.The three aspects constitute the measurement system of regional economy spatial variation.On this basis,the paper takes Zhejiang province as empirical research object,uses GDP as each county economic development level measure,quantitative analysis the situation of regional economy spatial variation in Zhejiang province from 1988 to 2008 by mathematical statistics method and the GIS methods.The empirical results show that the regional economy spatial variation in Zhejiang province presents ladder shaped expand,mainly has caused by the richer regions,and economic gravity centre constantly shifts.The result and the actual situation in Zhejiang province are quite similar.The measurement system has proved to be scientific and reasonable,and should to be popularizing in future research.
