中国政治型交易费用的规模测算与成因分解--一个基于分位数回归模型的实证研究

Measurement of Scale of Political Transaction Costs in China——An Empirical Research by Quantile Regression Model

作为交易费用的重要组成部分,我国的政治型交易费用在体制转型时期呈逐步上升趋势。通过建立分位数回归模型对其成因进行分解发现,经济发展水平、城乡差距对政治型交易费用有着正的边际效应,城市化率和市场化水平对政治型交易费用有着负的边际效应。由于经济发展带来的政治型交易费用比重扩大不可避免,所以要从提高城市化水平、缩小城乡差距、推进经济体制改革和政治体制改革等方面入手限制交易费用的过快增长。

As an important part of the transaction cost, the proportion of political transaction cost has a gradually rising trend in China. Using a quantile regression model, we find that the economic development and the gap between urban and rural areas have a positive marginal effect on the level of political transaction cost, but the degrees of urbanization and marketization have negative marginal effect. Based on these results, we should raise the level of urbanization, narrow the urban-rural gap and reform economic and political system to restrict the rapid growth of transaction costs.
