摘要:

以县域为基本单元,以GDP和人口为指标,运用绝对差异指标和相对差异指标等经典统计方法,以及可分解的泰尔指数和区域分离指数,分析了2002~2012年江苏省沿海经济发展差异的演变趋势和空间变化特征。研究结果表明:江苏沿海经济发展的绝对差异一直在不断扩大,相对差异基本呈缓慢缩小趋势。总体差异在波动中逐渐下降,其主要来源于区内差异,其中盐城区内差异贡献率最大。区域分离系数以2006年为拐点,呈倒“U”型变化特征,区域差异逐渐趋同。导致区域差异的原因主要是历史基础、区位条件和政策措施。空间结构的变化反映了政府发展战略的连续变化过程,体现了区域发展的非均衡性。

Abstract:

The article, taking counties as basic regiona1 study units, explores the spatial pattern of economic development in Jiangsu coastal region. The classical statistical methods and spatial statistical methods were used to analyze and measure time and space disparity of Jiangsu coastal economy in 2002-2012. The results showed: 1) The economic development of Jiangsu coastal area has been more and more open and concentration since Jiangsu coastal development became national strategy in 2009. The relative difference is slowly narrowing due to the difference rate of economic growth among three coastal cities, namely Nantong City, Yancheng City and Lianyungang City. The absolute difference of regional economy in Jiangsu coastal has been expanding due to the difference of development foundation and location conditions among three coastal cities. 2) From the Thail index change, the overall economic difference decreased gradually in Jiangsu coastal area. The mainly reason is rapid development of the economy in three coastal cities. It is groups difference rather than internal economic differences to result in Jiangsu coastal regional economic differences. The internal economic difference of Yancheng is the biggest in three coastal cities. 3) The interrelation between economic growth and spatial change of regional difference are analyzed based on regional separation index. The separation index presented an inverted “U” characteristics and the turning appeared in 2006. The main reason is regional conditions, historic foundation, development speed and policy measures.

Key words: regional differences, county level economy, Jiangsu Province, costal area
