【摘要】：本文立足于企业异质性理论，把微观企业作为研究对象，以《中国工业企业数据库》2007年的统计数据为样本。首先选取总体样本，利用Logit模型分析了以全要素生产率为代表的企业异质性以及出口对企业技术创新的影响；然后选取总体样本中既有出口又有新产品产值的企业样本，并用多元线性模型进行回归分析；最后又进一步讨论了在不同地区和所有制类型下，企业异质性与出口对企业技术创新的影响是否存在差异性。研究结果表明：1、对总体企业而言，全要素生产率的提高并不能提高企业的创新倾向，而对既有出口又有创新的企业而言，全要素生产率的提高能够增加企业的新产品产值；2、出口对企业创新具有正效应，即参与出口的企业与不参与出口的企业相比，具有更高的创新倾向，或者说出口额越大的企业，其新产品产值也越大；3、在其它代表企业异质性的特征中，企业规模和企业创新之间存在“U型”关系，也就是说，，大企业和小企业的创新倾向较高，而中型企业比较低。另外，企业平均工资与资本密集度等要素亦对企业产品创新活动有促进作用；4、与西部地区企业相比，全要素生产率对东部地区出口-创新企业的创新的影响程度会更大一些；平均工资、企业利润均对各种所有制类型的企业创新有促进作用，但这种促进作用在非国有企业中体现得比较明显。
[Abstract]:Based on the theory of enterprise heterogeneity, this paper takes microenterprises as the research object, and takes the statistical data of China Industrial Enterprise Database in 2007 as the sample. Firstly, the paper selects the total sample, analyzes the heterogeneity of enterprises represented by total factor productivity (TFP) and the impact of export on enterprise technological innovation by logit model, and then selects the sample of enterprises with both export and output value of new products in the total sample. At last, the paper discusses whether there are differences in the influence of enterprise heterogeneity and export on enterprise technological innovation under different regions and ownership types. The research results show that the increase of total factor productivity can not improve the innovation tendency of enterprises, but for enterprises with both export and innovation, the increase of total factor productivity can increase the output value of new products. (2) Export has a positive effect on enterprise innovation, that is, the enterprise participating in export has a higher tendency to innovate than the enterprise that does not participate in export. In other words, the larger the export volume, the greater the output value of new products; 3. Among the other characteristics representing the heterogeneity of enterprises, there is a "U type" relationship between enterprise size and enterprise innovation, that is to say, large and small enterprises have a higher tendency to innovate, while medium-sized enterprises have a relatively low tendency to innovate. In addition, the factors such as average wages and capital intensity also promote the innovation activities of enterprises. Compared with the enterprises in the western region, the total factor productivity will have a greater impact on the innovation of export-innovation enterprises in the eastern region. The average salary and profit can promote the innovation of enterprises of various ownership types, but this kind of promotion effect is obvious in the non-state-owned enterprises.
