【摘要】：文章基于2012年世界银行企业调查数据,从微观企业的角度出发,研究地方偏袒主义、研发投入与企业生产率的关系。结果表明:地方偏袒主义具有双管齐下的作用。地方偏袒指数每提高一个百分比,企业的生产率将提高0.031个百分比,研发投入每提高一个百分比,企业的生产率提升0.064个百分比。同时,基于门槛模型的估计结果发现,在政治偏袒程度较高的地方,地方企业研发对生产率的促进作用也更加明显。具体的,当地方偏袒指数跨越2.25的门槛值时,地方企业研发对生产率的促进作用由0.0428增至0.0536,且促进效应均在1%的置信水平上显著。
[Abstract]:Based on the survey data of the World Bank in 2012, this paper studies the relationship between local favouritism, R & D investment and enterprise productivity from the perspective of microenterprises. The results show that local favouritism plays a dual role. For every percentage increase in the local bias index, the productivity of the firm will increase by 0.031%, and the productivity of the firm will increase by 0.064% for each percentage increase in R & D investment. At the same time, the estimation results based on threshold model show that the promotion effect of local enterprise R & D on productivity is more obvious where the degree of political bias is higher. Specifically, when the local bias index exceeds the threshold of 2.25, the promotion effect of local enterprise R & D on productivity increases from 0.0428 to 0.0536, and the promotion effect is significant at the confidence level of 1%.
