国有控股大中型工业企业科技活动支出效果的实证研究

【摘要】 本文在分析企业技术创新能力提升途径的基础上,细分了国有控股大中型工业科技活动经费各类支出,并以2004-2004-2008年我国各地区国有控股大中型工业企业为样本,运用固定效用模型,实证分析了不同科技活动支出对创新的直接产出——专利申请数和间接产出——新产品销售收入的影响。实证结果显示:各项R&D经费支出对创新产出均具有显著的促进作用;其他科技活动经费内部支出具有专利产出导向性;其他各项技术活动经费对产出影响小且不显著。在上述结论的基础上,提出了相应的政策建议。更多还原

【Abstract】 Based on the analysis of the ways to promote enterprises’ technological innovation capabilities, this paper subdivides expenditures of scientific and technological activities of state- controlled large and medium- sized industrial enterprises, and uses the fixed effect model to analyze the impacts of expenditures of different scientific and technological activities on the direct output of innovations, i. e., the number of patent applications, and the indirect output, i. e., the total sales revenues of new products by using the panel data of the state- controlled large and medium- sized industrial enterprises from 2004 to2008. The results are as follows: firstly, different R&D expenditures all have positive effects on innovation outputs; secondly,the rest of intramural expenditures on S & T activities is oriented by patent output; finally, all the expenditures on other technical activities have little and insignificant impacts on outputs. On the basis of the above conclusions, this paper puts forward the corresponding recommendations.更多还原
