基于DEA的上海高技术产业结构优化研究

Study of High-tech Industrial Structure Optimization in Shanghai based on DEA Model

高技术产业发展已成为推进经济发展方式转变和产业结构调整的重要力量。为探寻资源最优配置状态,促进产业结构优化升级,基于投入-产出效率视角,运用EDA模型对上海高技术产业结构进行评价。结果表明:上海高技术产业总体产出效率良好,发展趋势为规模递增,但利润产出不足相当严重,且R&D内部经费投入、技术经费投入、人力资本投入均表现为产出不足;五大高技术行业发展呈现不同态势:电子制造产出效率不良,通信制造增长已现疲态,医药和医疗仪器制造资源配置走向优化但发展显得缓慢,航天航空制造产出效率低但规模递增趋势明显。高技术产业结构优化应以科技创新为导向,以提升产出效率为目标,合理加大投入力度。

The development of high - tech industry has become an important force in promoting the economic development pattern and adjustment of industrial structure. In order to explore the optimal allocation of resources, promote the optimiza- tion and upgrade the industrial structure, the article based on the input - output efficiency, uses EDA model to evaluate the Shanghai high - tech industrial structure. The results show that ： the overall output efficiency of the high - teeh industry is favorable, and it is in the ascending scale phase ; but the lack of profit output is quite serious, and the R＆D internal fi- nancial input, technical input of funds and human capital investment performance output are insufficient. The five high - tech industry development showed a different trend： electronics manufacturing output efficiency is poor; the communication manufacturing growth has been tired; the resource allocation of medicine and medical equipment manufacturing is towards optimization, but development seems slow; the aerospace manufacturing output efficiency is low, but ascending scale trend is obvious. The high - tech industrial structure optimization should be based on scientific and technological innovation and aim at improving output efficiency, and reasonably increasin~ investment.
