长三角城市群市场一体化水平测度与时空演变特征研究

Research on Market Integration Level Measurement and Spatio-temporal Evolution Characteristics of Yangtze River Delta Urban Agglomeration

以市场一体化相关理论为基础,采用相对价格等方法测度2010~2019年长三角城市群商品、劳动力和资本市场一体化指数,并运用变异系数法加权获得市场一体化总指数,进一步分析总体市场一体化及其分维度时空演变特征。研究结果表明:2010~2019年,长三角城市群商品市场一体化指数呈现波动上升趋势,资本市场一体化指数和总体市场一体化指数都呈现“M”型波动上升态势,而劳动力市场一体化指数总体上呈现下降态势;2010~2019年,上海商品市场一体化和劳动力市场一体化都较低,而资本市场一体化和总体市场一体化程度较高;2019年相比2010年,长三角城市群商品市场一体化、资本市场一体化和总体市场一体化指数呈现空间集聚效应,而劳动力市场一体化空间集聚效应不明显。这些结论对于加快推进长三角城市群市场一体化进程具有重要的指导意义和参考价值。

Based on the relevant theories of market integration,the relative price method and other methods were adopted to separately measure the market integration index of commodity,labor and capital in the Yangtze River delta urban agglomeration from 2010 to 2019.The variation coefficient method was applied to obtain the total index of market integration by weighting,so as to further analyze the overall market integration and its spatial-temporal evolution characteristics in different dimensions.The results show that:from 2010 to 2019,the commodity market integration index of the Yangtze River delta urban agglomeration shows a volatile upward trend the capital market integration index and the overall market integration index both show an upward trend of"M"type,while the labor market integration index generally shows a downward trend.From 2010 to 2019,Shanghai′s commodity market integration and labor market integration are relatively low,while its capital market integration and overall market integration are relatively high.In 2019,compared with2010,the commodity market integration,capital market integration and overall market integration index of the Yangtze River delta urban agglomeration present spatial agglomeration effect,while the spatial agglomeration effect of labor market integration is not obvious.These conclusions have important guiding significance and reference value for accelerating the market integration process of Yangtze River delta urban agglomeration.
