新疆科技投入对区域经济增长的贡献度分析——基于扩展C-D生产函数和DEA分析法

运用扩展C-D生产函数的索洛余值法,计算出新疆1994年至2009年RD经费投入对区域经济增长的总体贡献率为4.58%,远低于全国40.71%的平均水平,对区域经济增长的拉动作用小;其次从投入和产出两方面构建科技投入对区域经济增长的贡献度评价指标体系,运用数据包络分析法(DEA分析法)对全国30省市科技投入的贡献度进行评价,得出新疆科技投入综合效率为0.467,低于全国平均水平,技术效率和规模效率无效导致其贡献度很低,且呈现科技投入产出规模效益递减的趋势。因此,在现有科技投入规模下,应合理配置科技资源,提高科技资源的利用效率,将科技投入最大程度地转化为对经济增长的贡献产出,发挥对经济的推动作用。

A study on contribution of science and technology inputs to regional economic growth in Xinjiang-Based on improved C-D production function and DEA method

The overall contribution of R&D inputs to regional economic growth from 1994 to 2009 in Xinjiang is 4.58% calculated by improved C-D production function, which is lower than the national average of 40.71%. The index systems of contribution of R&D inputs to regional economic growth were built concerning both inputs and outputs. The data envelopment analysis (DEA analysis) was used to evaluate the contribution of investment in science and technology in the 30 provinces. The conclusions are that the overall efficiency of investment in science and technology in Xinjiang is 0.467, lower than the national average, the invalid of technical efficiency and scale efficiency lead to the lower of contribution, and the input-output scale of scientific and technological presents a decreasing trend. Therefore, under the size of the existing investment in science and technology, we should allocate the scientific and technological resources reasonably, improve the efficiency in the use of scientific and technological resources, and make sure the greatest degree of transformation of the science and technology investment to the economic growth.
