摘要
以2012-2016年安徽省市级工业企业R&D投入产出数据为样本,利用DEA-BCC模型度量企业研发技术效率,在选择和处理投入指标时,将R&D经费内部支出分解为资产性支出与经常费用支出;从理论上分析政府补贴与融资约束对企业研发投资以及研发技术效率的影响,并分别建立实证检验模型。结果表明:企业研发技术效率相对较高,但空间差异较大,在时间上没有表现出技术进步的特征;政府补贴对企业研发投资具有显著的促进作用,但缺乏弹性,融资约束对企业研发投资具有抑制作用,但不显著;融资约束对企业研发技术效率的提高具有显著的负向影响,政府补贴强度对企业研发技术效率的提高具有微弱的抑制作用。
Taking the R&D input and output data of municipal industrial enterprises in Anhui province from 2012 to 2016 as a sample, the study uses the DEA-BCC model to measure the R&D technical efficiency, and decomposes the internal R&D expenditures into asset expenditures and current expenses when selecting and processing input indicators.Besides, the study also analyzes the impact of financial subsidies and financing constraints on enterprise R&D investment and R&D technical efficiency theoretically, and then establishes the empirical test models respectively. The results show that the efficiency of enterprise R&D technology is relatively high, but the spatial difference is large and it does not show the characteristics of technological progress in time;government subsidies have a significant role in promoting enterprise R&D investment, but lack flexibility, and the financing constraints have an inhibitory effect on enterprise R&D investment, but it’s not significant;financing constraints have a significant negative impact on the efficiency of enterprise R&D technology, the intensity of government subsidies has a slight inhibitory effect on the improvement of enterprise R&D technical efficiency.
