基于泰尔指数的江苏省区域差异多指标测度

基于泰尔指数测度方法对江苏省1978—2004年人均GDP、人均农业总产值、人均城乡居民储蓄存款和人均社会商品零售总额等4方面指标的区域差异进行测度分析,得出江苏省人均农业总产值的差异变化平缓且略有降低、人均城乡居民储蓄存款变化趋势呈U型、人均GDP和人均社会商品零售总额的差异不断扩大。除人均农业总产值外,江苏省三大区域间的差异程度均呈现不断扩大趋势,且对区域差异影响较大。同时,三大区域内部的差异也各不相同,苏南地区除人均农业总产值差异较大外,其余3项指标的差异程度较小,与改革初期相比均呈缩小趋势;苏中地区各项指标的差异程度变化不大;而苏北地区除人均农业总产值外其余3项呈现扩大趋势,且区域内部差异最大。

ANALYSIS OF REGIONAL INEQUALITY IN JIANGSU PROVINCE BY MULTI-TARGET MEASURE BASED ON THEIL INDEX

The measure method of Theil index is suggested to analyze the changes of regional inequality in Jiangsu Province in this article,which chooses four targets that includes per capita GDP,the total value of agricultural output per person,the saving deposit of inhabitant in the city and countryside per person, the total value of retail sales of social commodity from 1978 to 2004.It is showed that regional inequality on these economic indicator total in the Jiangsu Province is changing unceasingly in the paper.The change of the total value of agricultural output per person is gentle,which also has slightly reduced;the change curve of the inhabitant saving deposit in the city and countryside per person shows U shape;both regional inequality of per capita GDP and regional inequality on the total value of social commodity retail sales expand unceasingly.Regional inequality of four targets besides the total value of agricultural output per person among three regions of Jiangsu Province all increase unceasingly,the effects of which on regional inequality in Jiangsu Province are the bigger.In the interiority of three regions,the changes of regional inequality of these four targets are all different.In the interiority of south Jiangsu,the interior regional inequality of these targets besides the total value of agricultural output per person is the smallest and has reduced as compared with the initial stages of the innovation and opening periods.The change of interior inequality in central Jiangsu on these four targets is not obvious.However,in north Jiangsu the interior inequality of these four targets all present the expanded tendency besides the total value of agricultural output per person.Moreover,in north Jiangsu,the changes of regional inequality of these four target besides the total value of agricultural output per person expand unceasingly,and the degree of regional interior inequality is the biggest.
