产品价格及要素边际产出空间差异的波动特性可直观反映市场一体化演化趋势。在采用“一价定律”和空间杜宾回归模型对产品及要素市场整合程度进行定量分析后发现,目前我国产品市场一体化程度较高且正不断加深;劳动力市场一体化程度自2003年开始由趋于弱化转向趋于加深;资本市场分割程度在最近20年内更加严重;技术要素边际产出差异呈现先降后升的态势,技术未能有效转向高报酬率区域;一体化土地要素市场尚未建立,在现行用地供给计划配给、土地发展权不允许跨地区交易条件下,我国土地利用正经受严重的效率损失。
The fluctuation characteristics of product price and marginal output space of factors can directly reflect the evolution trend of market integration. Using the “one price law” and the spatial DUBIN regression model to quantitatively analyze the degree of integration of products and factors in the market, we find that the integration of product markets in our country is high and is deepening at present. The degree of labor market integration has been increasing since 2003 The trend of capital market segmentation has become more serious in the recent 20 years; the marginal output of technical factors shows the trend of first decreasing and then rising; the technology fails to effectively shift to areas with high rates of return; the integrated land factor market Under the condition that the current land supply rationing is not provided and the land development rights do not allow cross-border transactions, land use in our country is experiencing serious loss of efficiency.
