中国产业结构整体同构化趋势研究——基于成分数据统计

已有产业结构同构化指标适用于两两地区之间的同构化测度,缺乏从整体角度提出多个地区的测度方法。运用成分数据统计理论,在三元图直观反映产业结构整体演变的基础上,提出结构中心和结构离散度指标来整体测度产业结构同构化,并对中国31个省份以及东部、中部、西部和东北地区不同区域的产业结构同构化进行实证分析。研究表明:中国31个省份整体同构化程度比较稳定,东部区域同构化程度最低,而不同区域则呈现出不同的同构化趋势。

Research on the Global Isomorphic Trend of China's Industrial Structure:Based on Compositional Data Statistics

The existing isomorphic indexes of industrial structure are applicable to measure isomorphism between two regions.From the whole perspective,this paper proposes a new method to measure the isomorphism of industrial structure in many regions.Based on the theory of compositional data statistics,this paper uses the ternary diagram to reflect the whole evolution of industrial structure and proposes the structure center and the structural scatter degree to measure the global isomorphism of industry structure.Using those indexes,this paper has analyzed empirically the global isomorphism of industrial structure of 31 provinces and cities in China and the Eastern,Middle,Western and Northeastern regions .The research not only shows that the global isomorphism of the 3 1 provinces in China is relatively stable and the Eastern region is the lowest degree in global isomorphism.It but also shows different regions show different isomorphic trend.
