基于DEA方法的吉林省高技术企业创新效率研究

The innovation efficiency of hi-tech enterprises in Jilin Province based on DEA method

首先基于创新效率评价的现有研究成果,构建高技术企业创新效率评价指标体系与模型。然后结合实地调研获取的数据,运用DEA方法,从效率、有效性、规模收益及投影分析四个方面,对吉林省151家高技术企业创新活动进行了评价与分析。结果表明,吉林省高技术企业创新综合效率偏低,不同类型企业创新效率差异较大,规模效率是导致创新综合效率偏低的主要因素;多数企业呈规模报酬递增态势,科技活动人员和科技活动经费投入过少是企业规模效率偏低的主要原因。最后提出企业创新效率改进目标、方案和相应政策建议。

First, based on existing research, the research on the construction of evaluation index system and model for the inno- vation efficiency of hightech enterprises is proceeded, and then the innovation activity of 151 high -tech enterprises in Jilin Province is evaluated and analyzed in terms of efffciency, effectiveness, returns to scale, and projection analysis by using DEA method and the data acquired though field survey. The result shows that the general level of innovation efficiency for high - tech enterprises is low, with significant discrepancy between different types of enterprises ; and scale efficiency is the main factor that leads to low innovation efficiency; for most enterprises, returns to scale is increasing, and input of S＆T personnel and funds is insufficient, leading on to low scale efficiency. Finally, the objective, program, and corresponding policy proposals to improve innovation efficiency of high - tech enterprises are offered on the basis of empirical analysis.
