中原城市群产业分工与经济联系研究

The Study on the Industrial Division of Labor and the Economic Linkages in Zhongyuan Urban Agglomerations

运用产业区位熵,研究发现目前中原城市群:①在19大类产业上的分工不明朗,各城市的专业化产业相似程度高;②在2位数工业产业上的分工层次也不高,各城市的主要专业化产业大多以当地矿产或农产品资源为基础.运用加入反映两城市产业分工的克鲁格曼指数的引力模型,研究发现:①2000年以来,中原城市群的内部经济联系不断加强,网络型城市开始浮现;②目前,以郑州市为中心的中原城市群的经济联系空间可分为4个不同等级;③在城市群经济联系中,尽管"距离衰减"规律仍在起作用,但城市间的产业分工可能也是一个重要影响因素.

By using the industrial location quotient, it was found that the level of the division of labor in 19 industry categories of Zhongyuan Urban Agglomerations is not high, the industrial specialization is similar and the level of the division of labor in the 2-digit industry is also not high, the eity＇s main specialized industries are mostly based on the local agricultural or mineral resource in Zhongyuan Urban Agglomerations. By joining the Krugman＇s index which reflects the industrial division of labor between the two cities into the gravity model, it was found that the economic linkages is strengthened in Zhongyuan Urban Agglomerations from 2000, a network-based city begin to appear. At present, the economic linkage space of Zhongyuan Urban Agglomerations can be divided into 4 different levels according to the linkages between the two cities. Finally, The research indicated that the range attenuation rule plays an important role in the economic linkages between cities, but the industrial division of labor becomes an important factor.
