分析了产业的多样化和专业化对区域市场一体化的作用机制,利用相对价格方差度量了京津冀市场一体化的程度,并通过建立面板数据模型实证检验了产业的相关多样化、无关多样化和专业化对市场一体化进程的影响效应。结果表明:京津冀的产业多样化更突出地表现为无关多样化,且专业化水平较低;产业的相关多样化有利于市场向着一体化的方向发展,而无关多样化则对市场一体化有明显的阻碍作用;专业化对市场一体化的促进作用不明显;京津冀产业的无关多样化和低水平专业化已对其市场一体化进程产生了一定的负面影响。
Analyzes the mechanism of diversification and specialization of industries on the integration of regional markets, measures the extent of market integration in Beijing, Tianjin and Ji using the relative price variance, and empirically tests the related diversification of industries through the establishment of panel data model, Impact of Specialization and Specialization on Market Integration Process. The results show that the industrial diversification in Beijing-Tianjin-Hebei region is more marked with irrelevant diversification and lower level of specialization; the diversification of industries is conducive to the development of the market in the direction of integration, while the diversification is irrelevant to market integration Which has a clear impediment to the market. The promotion of specialization on market integration is not obvious. The unrelated diversification and low-level specialization of the industries in Beijing, Tianjin and Hebei have had a certain negative impact on the process of market integration.
