长三角省际贸易强度与制造业同构的关系分析

The Analysis of the Correlations between the Intensity of Inter-Provincial Trade and the Structural Homogeneity of Manufacturing in Delta Area of Yangtze

本文给出了一种近似衡量地区间贸易壁垒强度的方法,利用该方法测度了历年来长三角的省际贸易强度。同时,文中还引入了一个结构重合度指数,利用该指数计算了历年来长三角制造业的同构度。经过单位根检验与协整检验后,对两个序列进行了回归分析。结果表明,省际贸易强度与制造业同构度之间存在着明显的负相关关系。

Based on the Location Quotient, a method that can measure the Intensity of Inter-provincial trade was put forward. A structural superposition index that can measure the degree of structural homogeneity of manufacturing was introduced. The Intensity of Inter-provincial trade and the degree of structural homogeneity of manufacturing in Delta Area of Yangtze were calculated. After unit root test and eointegration test, regression was performed and their quantitative relation was worked out.. The analytic results showed that the Intensity of Inter-provincial trade had remarkable negative correlation with the degree of structural homogeneity of manufacturing.
