摘要
笔者运用中国制造业数据对市场结构与产业的技术特征之间的关系进行了实证研究。通过运用两类产业的面板数据模型,笔者发现高集中度产业和低集中度产业与产业的技术特征之间的关系有着显著的区别:平均规模对高集中度产业的市场集中度有着显著正影响,而对低集中度产业的市场集中度有着显著负影响;两类产业的技术替代率对市场集中度的影响也不相同,其中高集中度产业的边际技术替代率对市场集中度的影响并不显著。这些区别对于针对性地制定产业政策以改善产业结构有着重要的意义。
The paper investigates the relationship of market structure and the technique characteristics of industries on empirical research basis by using the data on manufacturing industry in China. We find higher- concentration industry and low- ooncentration industry have significant difference with the technique characteristics of industries： average scale has significant positive effect to the market concentration of high- concentration industry, but it has significant negative effect to low- concentration industry. However, the marginal rate of technical substitution of two industries has oppctsite effect to concentration,where high- concentration industry＇s impact to market concentration is not significant. These differences will tell us how to establish industry policy and how to improve industry structure.
