#br# 行政权分割、市场分割与城市经济效率*——基于计划单列市视角的实证分析
ADMINISTRATIVE POWER SEGMENTATION, MARKET SEGMENTATION AND ECONOMIC EFFICIENCY——An Empirical Study Based on Separateplanning Cities of China

摘要 针对计划单列市经济发展的特殊表现，本文利用2001—2015年市级面板数据，使用系统GMM方法，实证分析了行政权分割、市场分割对城市经济效率的影响。本文研究发现：（1）行政权分割抑制了城市间的溢出效应，省会作为省内中心城市对其他城市的经济效率具有正向溢出效应，而对计划单列市则呈现抑制作用；（2）市场分割对经济效率的影响呈现非线性关系，即在初期其有利于经济效率的提升，但超过一定门槛值后将会导致经济效率下降。
Abstract： Based on the special phenomenon of separateplanning cities in China, this paper applies the panel data of city level from 2001 to 2015 and the method of system GMM to analyze the effect of administrative power segmentation and market segmentation on the urban economic efficiency This empirical results shows as follows: (1) The segmentation of administrative power inhibits the spillover effect from central city; (2) market segmentation on economic efficiency shows an nonlinear relationship, it is positive to economic efficiency at the beginning, but then turn negative when the market segmentation beyond a threshold value
