制造业产业聚集与纵向分离的实证研究

探讨中国的制造业地理集中程度与纵向分离程度的关系。利用整理所得的产业区域资料,发现产业集聚中心的纵向分离程度,比产业集聚中心外的区域的纵向分离程度要高;而比较地理集中的产业,其产业聚集中心内外纵向分工程度的差异水平,高于整体制造业与地理不集中产业的差异水平。同时也发现,当产业地理集中度随着邻近同产业、相关产业与其他产业的就业人数增加而提高时,纵向分离程度也会随着提高。实证的结果进一步论证了,产业的地理集中,可以降低厂商在市场上的交易成本,进而提高交易效率与产业纵向分离程度。

Industrial Clustering and Vertical Disintegration of Manufacturing Indwstry

This paper aims to explore the relationship between geographical concentration in China's manufacturing industries and the degree of vertical disintegration.Through searching relative information and identifying industrial district resources,this paper proves that the degree of vertical disintegration within industrial clustering district is much closer than outside.Furthermore,corresponding to those unfocused industry districts,there are huge level differences in specialization degree in geographical concentrating industry.And we also found that the degree of vertical disintegration will be improved with the improvement of industrial geographic concentration,which following the increase in employ- ment in neighboring and related industries.The empirical results further demonstrated that the industry's geographic concentration can reduce the cost of transactions in the market and improve the efficiency and industry vertical disintegration as well.
