摘要
按照OECD的标准,将我国28个制造业划分为高技术、中高技术、中低技术和低技术制造业四类。采用面板数据模型,系统比较了四类制造业大中型工业企业的创新效率及其影响因素。结果表明:四类制造业大中型工业企业的人均科技活动经费支出对其创新效率均具有显著的正向影响,并且相关系数随着制造业技术含量的提升而增大;人均科技活动经费支出和人均固定资产对低技术制造业大中型工业企业的创新效率具有显著的正向影响。
According to the standard given by OECD,this paper categorizes 28manufacturing industries into 4groups,namely high-technology industry,medium-high-technology industry,medium-low-technology industry and low-technology industry.And then it adopts the panel data model to analyze and compare the innovation efficiencies of 4groups of large-middle industrial enterprises.The result shows as follows：the ST expenditures of 4groups of large-middle industrial enterprises have positive effects on innovation efficiency,and the innovation efficiency is growing steadily with the increase of the technical content;ST expenditure per capital and fixed asset per capital have positive significant effects on the innovation efficiency of large-middle industrial enterprises in low-technology industries.
