桑植县产业结构和经济增长的灰色关联分析

根据“配第-克拉克定理”,地区产业结构发展的最高阶段呈“三、二、一”形式的结构,即第三产业在国内生产总值中所占比例最大,第二产业次之,第一产业最后的产业结构形式。数据显示,桑植县目前产业结构中出现第一和第二产业所占GDP比例相差不大,第三产业遥遥领先的局面。产业结构呈现明显的不合理。运用灰色关联分析方法对桑植县产业结构与经济增长进行研究,分析了桑植县三次产业与GDP之间的灰色关联度,发现第三产业对桑植县的经济增长的作用最为明显,关联度最高,第二产业与经济的关联度最低,这与“三、二、一”产业结构形式相违背,于是针对第二产业的发展进行研究,在此基础上,为促进桑植县产业结构优化与经济增长提供了相关的对策建议。

Gray correlation analysis of industrial structure and economic growth in Sangzhi County

According to the theorem of "Petty-Clarke", the highest stage of the development of regional industrial structure is in the form of "three, two, one" structure, namely the tertiary industry accounts for the largest proportion of GDP, followed by the secondary industry, and the primary industry is the last form of industrial structure. Data showed that the current industrial structure of Sangzhi County, the proportion of GDPaccounted for by the primary and secondary industries was not much different, and the tertiary industry was far ahead of the situation. The industrial structure presents obvious irrationality. Gray correlation analysis method was used to study the industrial structure and economic growth of Sangzhi County, the gray correlation between the three industries and GDP in Sangzhi County was analyzed, and finds that the tertiary industry plays the most obvious role in the economic growth of Sangzhi County, with the highest correlation, and the secondary industry has the lowest correlation with the economy, which is contrary to the form of "three, two, one" industrial structure.So,the development of the secondary industry is researched, based on which, relevant countermeasures are provided to promote the optimization of industrial structure and economic growth in Sangzhi County.
