从企业规模、市场外向度两大视角对我国制造业20个细分行业的集聚程度进行实证分析。研究发现:大部分行业的集聚程度在总体上呈现出不断强化的趋势,行业市场外向度的提高能对其地区集聚形成显著的促进作用,而企业相对规模则与产业集聚呈现出“U”型特征;对高、低集聚行业分类考察发现,市场外向度的正向作用仅在低集聚行业中十分显著,而企业规模与产业集聚之间在低集聚行业中所呈现出“U”型特征而在高集聚行业中表现出倒“U”型关系的现象使得两者在整体上呈现倒“S”型关系。研究发现对制定和实施我国的产业集聚与空间布局政策均有相应的参考意义。
From the perspective of firm size and market extroversion, this paper empirically analyzes the degree of agglomeration of 20 segments in manufacturing industry in China. The result shows that the agglomeration degree of most industries shows an increasing trend in general, and the improvement of the outward degree of the industrial market can significantly promote the regional agglomeration, while the relative scale of the enterprises and the industrial agglomeration show “U It is found that the positive effect of market-orientedness is only significant in the low-agglomeration industry, while the relationship between firm size and industrial agglomeration is low in the agglomeration industry. However, in the high-agglomeration industry, the phenomenon of ”U“ -type relations has been shown in the characteristics of the high-agglomeration industries, resulting in a ”S" -type relationship between the two as a whole. The research found that there is a corresponding reference meaning for the formulation and implementation of China’s industrial agglomeration and spatial distribution policy.
