垂直分工、产业集聚与专业化优势——兼论长三角地区的制造业优势格局

产业集聚、垂直分工和专业化生产，是一个地区产业优势的反映。垂直分工与产业集聚、专业化生产之间呈正相关关系，产品“生产链”解体和中间品生产网络体系的生成导致了垂直分工，产业集聚演进推动了产业链的中间产品环节垂直分工的展开，形成了专业化生产的优势。上海制造业的垂直分工水平总体落后于浙苏两省，但一些高科技制造业上海仍处于优势地位。浙江的制造业总量不如江苏，但是浙江的制造业总体的垂直分工水平略高于江苏，浙江制造业的多数部门具有高于江苏的专业化生产优势。

Vertical Division of Labor, Industry Cluster and Specialization——Also on Structure of Industry Advantage of the Yangtze River Delta Region

What results in the vertical integration is the industry chain integration and the production network of intermediate goods. The research is based on the analysis of Chinese manufacturing industry data of 31 provinces. We prove that there is close connection between vertical disintegration, industry agglomeration and specialization. The increase of industrial cluster will impulse the vertical disintegration of industry chain and form product specialization. Industry agglomeration, vertical disintegration and specialization can be considered as the industry advantage. Having this as the basis, we go on analyzing the structure of industry advantage of the Yangtze River Delta Region. Compared to Shanghai, Zhejiang and Jiangsu have the advantage in mass departments of manufacturing industry.
