| 摘 要： | 本文以2009-2017年我国农业企业的混合截面数据为样本，构建SSBM-网络DEA模型测度其科技成果转化效率，并在此基础上从时间-空间角度对其演变趋势与收敛性进行了探究。研究结论如下：（1）只有极少数农业企业的科技成果转化效率达到并超过1，农业企业科技成果转化效率均值为0.421，效率损失情况较为严重；农业企业的科技成果转化效率集中分布在0.300，0.500]区间内，科技成果转化效率高于0.500的农业企业较少。（2）从时间趋势看，农业企业科技成果转化效率整体呈现递增趋势，但存在较强的经济短波现象，农业企业科技成果转化效率受政策影响较大。（3）从空间趋势看，中部地区农业企业科技成果转化效率均值最高，其次是西部地区与东部地区，三大区域农业企业科技成果转化效率之间无显著差异，东部及西部农业企业科技成果转化效率存在向中部地区农业企业追赶的态势，三大区域呈现稳态增长。基于此，本文提出应充分发挥政府法律规范、制定的积极作用以及协调区域经济发展水平等政策建议。

| Abstract: | Based on the mixed cross-section data of China''s agricultural enterprises in 2009-2017, this paper constructs the SSBM-network DEA model to measure the conversion efficiency of its scientific and technological achievements, and on this basis, it explores its evolution trend and convergence from a time-space perspective. The conclusions of the study are as follows: (1) Only a few agricultural enterprises have achieved a conversion efficiency of scientific and technological achievements of more than one, and the average efficiency of scientific and technological achievements in agricultural enterprises is 0.421, and the efficiency loss is more serious; the conversion efficiency of agricultural enterprises'' scientific and technological achievements is concentrated in 0.300 In the interval of 0.500], there are fewer agricultural enterprises with higher conversion efficiency of scientific and technological achievements than 0.500. (2) From the perspective of time trend, the transformation efficiency of scientific and technological achievements of agricultural enterprises shows an increasing trend as a whole, but there is a strong economic short-wave phenomenon. The transformation efficiency of scientific and technological achievements of agricultural enterprises is greatly affected by policies. (3) From the perspective of space trends, the conversion efficiency of scientific and technological achievements of agricultural enterprises in the central region is the highest, followed by the western region and the eastern region, and there is no significant difference between the conversion efficiency of scientific and technological achievements of agricultural enterprises in the three regions. Eastern and western agricultural enterprises The efficiency of scientific and technological achievements has been catching up with the agricultural enterprises in the central region, and the three regions have shown steady growth. Based on this, this paper proposes that the government should give full play to the government''s legal norms, formulate positive effects, and coordinate regional economic development levels. |
