中国区域制造业结构同构的变化及分析

Changes and Analysis of Structural Isomorphism of Regional Manufacturing Industry in China

根据各省(区、市)制造业分行业的总产值和增加值数据,从区域分工和专业化的视角出发,计算区域产业结构同构系数和区域产业专业化指数,分析我国区域间产业结构同构程度变化的历史轨迹发现,区域产业同构程度不断下降,区域专业化程度不断提高。2012年我国区域产业结构同构程度与美国20世纪80年代末相当,可见我国区域产业结构同构程度仍然高于美国。为降低不合理的区域产业同构和促进区域产业的专业化发展,应降低区域间交易成本,加快改革步伐,提高对外开放质量。

According to the output value and added value of individual manufacturing sectors of various provinces(autonomous regions and municipalities),this paper calculates the regional industrial structure isomorphism coefficient and regional industrial specialization index from the perspective of regional division and specialization.The historical path of the isomorphism degree of inter-regional industrial structure in China shows that the isomorphism degree of regional industry is decreasing,and the degree of regional specialization is increasing.In 2012,the isomorphism degree of China’s regional industrial structure was comparable to that of the United States in the late 1980s,indicating that China’s isomorphism degree was still higher than that of the United States.In order to reduce the unreasonable isomorphism and promote regional specialization,it is necessary to reduce the interregional transaction cost,speed up the reform and improve the quality of opening-up.
