中国制造业的市场集中、地理集聚与企业绩效

本文研究我国制造业的市场结构与地理分布对企业全要素生产率的影响.以中国工业企业数据库的大样本数据为基础,采用LP法计算企业生产率,构造市场集中度指标和地方化经济、城市化经济两个集聚指标,进行了多方位的计量检验.研究结果表明,制造业的市场集中不利于企业生产率的提高,代表专业化水平的地方化经济促进了企业生产率的提升,度量行业间多样化集聚的城市化经济对企业生产率没有显著的影响.市场集中对出口企业的负面影响不明显,控制市场集中和地理集聚后,出口企业生产率高于非出口企业,出口的“生产率悖论”并不存在.

Market Concentration,Spatial Agglomeration and Firms's Performancein Chinese Manufacturing Industry

This paper explores the relationship between the market structure, geographic agglomeration and firms's economic performance.Using the data of Chinese manufacturing firms from 2000 to 2007, we measure the firm-level productivity through LP method, and set up indicators for the measurement of concentration and agglomeration status to test this relation through various regression analysis.Empirical result show that localization economy significantly increases firms's productivity, while urbanization economy, in most cases, does not exert a significantly positive effect.At the same time, productivity is negatively influenced if the market structure presents high degree of monopoly.
