成渝产业带产业结构的相似性及其结构转换力分析

ON INDUSTRIAL STRUCTURE SIMILARITY AND THE ABILITY OF STRUCTURAL ADJUSTMENT IN CHENGDU AND CHONGQING REGIONS

利用数据方差、相关系数和相似系数指标对成渝产业带这一长江上游具有重要地位的经济区域进行了产业结构特征分析。从产业部门相对变动的总体方差看,第一产业在国内生产总值中的份额变动幅度最大,即第一产业在国内生产总值的比重均衡性最弱,第三产业次之,第二产业最小;从相关系数看,重庆与整个产业带地区,自贡与整个产业带地区,成都与全产业带地区的产业结构相关系数相对较高,即这些区域对整个产业带产业结构影响程度较高,除此之外自贡与重庆之间的产业结构相同程度也较高,相关系数相对较小的是成都与内江、成都与自贡、内江与自贡、内江与重庆,其产业结构的雷同程度相对较低;产业结构相似性程度分析的结果与相关系数的描述基本一致。并对该地区产业结构的转换能力进行了量化,成都、重庆转换调整能力强,而自贡、内江调整能力相对较弱,地域分布上表现产业带两头强、中间弱的明显特征。转换能力的量化结果表明产业结构转换能力依赖于经济发展水平,特别是与人均GDP。

The paper analyses the natures of industrial structure in Chengdu Chongqing region,which is of important strategical status in upper reaches of the Yangtze River,in terms of the indices of data variances,relative coefficient and similar coefficient.Analysis shows that the largest value of data variance is primary industry,next comes the tertiary industry,while the second exhibits the least value of data variance.Between Chongqing and the whole of industrial corridor,Zhigong and the whole of industrial corridor,Chengdu and the entire industrial corridor,Zhigong and Chongqing are more similar in industrial structure than these between Chengdu and Neijiang,Chengdu and Zhigong,Neijiang and Zhigong,Neijiang and Chongqing,based on relative coefficient.On the other hand,the result of similiarity analysis almost is the same as that of the relative coefficient method.Mean while,the ability of industrial adjustment is analysed likewise with quantitative method.It is very obvious that the ability of industrial adjustment in Chengdu and Chongqing regions are stronger than that of Zhigong and Neijiang regions.Finally,the conclusion is drawn that the ability of industrial adjustment is closely related to the level of economic development;per capita gross domestic product,the proportion of tertiary industry,industrial advance degree and industrial productive effciency obviously contribute to the ability of industrial adjustment in Chengdu and Chongqing industrial corridor.
