摘要
借鉴经济学中弹性理论,将R&D活动产出指标变化率与投入指标的变化率的比值定义为弹性系数,选取我国31个省市2009-2013年R&D投入与产出数据,在考虑滞后期的基础上对比分析各省市R&D产出对投入的敏感性,并探究R&D产出对投入的弹性系数的动态演变过程。研究表明:我国大多省市R&D投入对专利授权量转化效率高呈规模报酬递增;科技论文数量对R&D人员全时当量的弹性系数受各省市高等院校和科研机构数量影响较大;各省市R&D经费投入对科技论文数量产出的转换效率低呈规模报酬递减;对比2009年和2013年数据,各省市R&D投入稳步增加,但弹性有下降趋势。因此,我国各省市科技政策制定工作的侧重点应该逐步从不断增加R&D投入向合理调整R&D资源的分配组合倾斜,推动各个级别的科研经费的改革与调整迫在眉睫。
Based on elastic theory in economics,The R＆D output rate and the ratio of R＆D input rate is defined as elastic coefficient.To analyze the sensitivity of R＆D output,we select R＆D input and output data of 31 provinces in china as sample. We also studied dynamic evolution of Elastic coefficient with data from 2009-2013. The result shows that the efficiency of converting the R＆D input to the patent grant is high in most provinces of china. The number of college and scientific institution has a significant impact on the number of papers. The efficiency of converting the R＆D expenditure to papers is poor. Compared with the date of 31 provinces in 2009,the R＆D input increase steadily while the elasticity reduced. The intensity of R＆D investment and the allocation of R＆D resources are equally important for science and technology innovation.
