文章在中国高技术制造业整体和细分层面上分析了中国地级及以上城市高技术制造业分工的演化特征,并通过2003年至2011年的面板数据实证检验了中国高技术制造业相对专业化指数对本地产业效率的影响。研究发现:中国高技术制造业东部与中西部空间分工的差异化程度正在扩大;高技术制造业专业化程度随城市规模等级的扩大而下降,同时特大城市在高技术产业中的主导地位不断上升,各细分行业的产业中心不再倾向于集中在超大型城市中;在高技术制造业整体上专业化程度与产业效率呈现显著的负相关关系,在不同城市规模组别中,除超大型城市中专业化程度与高技术制造业的产业效率不存在显著的相关性外,其他规模等级的城市均呈现出了显著的负相关关系。
The paper analyzes the evolution characteristics of the high-tech manufacturing division in China’s prefecture-level cities and above at the level of the high-tech manufacturing industry in China as a whole and in detail, and empirically tests the relative professions of China’s high-tech manufacturing industry through the panel data from 2003 to 2011 Impact of index on local industry efficiency. It is found that the degree of differentiation of the division of labor between the east and the midwest of China’s high-tech manufacturing industry is widening. The degree of specialization of high-tech manufacturing industry declines with the expansion of urban scale, and the leading position of mega-cities in high-tech industries is constantly rising , The industrial centers in each sub-industry no longer tend to be concentrated in mega-cities; in the overall high-tech manufacturing industry, there is a significant negative correlation between the degree of specialization and industrial efficiency. In different urban scale groups, There is no significant correlation between the degree of specialization in the cities and the industrial efficiency in the high-tech manufacturing industries. Other cities in the scale have shown significant negative correlations.
