摘要
研发效率是衡量企业创新能力的关键因素。基于2012—2015年面板数据,运用三阶段DEA模型,在控制环境因素的基础上对我国36家农业类上市公司的研发效率进行了测度和分析。结果表明:过于集中的股权结构会加剧公司投入冗余,而政府补贴则有助于减少研发投入浪费;在剔除环境因素、随机误差的影响后,大多数公司的综合技术效率和规模效率下降,且普遍处于规模递增状态,说明规模扩张仍是研发效率提升的重要瓶颈,因此要提高农业公司的研发效率。
R&D efficiency was the key factor to measure the innovation ability of enterprises. Based on panel data(2012 - 2015) ,the R&D efficiency of 36 agricultural listed companies in China were measured with controlling the environment factors and the random error using the three - stage DEA model. The results showed that concentration of ownership structure would increase the company into redundancy, while the government subsidy could help reduce the waste of R&D, the comprehensive technical efficiency and the scale efficiency were reduced, and generally in a state of increasing scale after eliminating the influence of environment factors and random error, which showed that scale expansion was still the important bottleneck of improving R&D efficiency. In the end, it put forward some suggestions to improve the R&D efficiency.
