摘要: 为了研究农业科技进步对我国区域农业经济增长的影响,揭示农业科技进步在农业生产和农业经济增长中的作用机理,探讨农业科技进步对农业经济增长影响的地区差异及其产生原因。基于C-D生产函数的一般形式,建立固定效应变参数面板模型,对相关面板数据变量进行平稳性检验和协整检验,并对模型的相关参数进行回归估计。在此基础上就农业科技进步对我国区域农业经济增长的影响进行全面详细的实证分析。通过对相关要素贡献率的分析,较好地解释了农业科技进步对我国区域农业经济增长的影响机制。研究表明:农业科技进步贡献率存在明显的区域差异,反映出我国农业科技发展水平呈现区域不均衡状态;农业科技进步在我国农业经济增长过程中所起的作用仍然较小,我国农业经济增长所依赖的传统高投入、高消耗、低产出、低效益的粗放式增长方式并没有发生根本性的改变。

Abstract: In order to study the impact of agricultural science and technology on regional agricultural economic growth, reveal the function mechanism of agricultural science and technology in agricultural production and agricultural economic growth, explore the regional differences of the effect of progress of agricultural science and technology on the economic growth of agriculture and its causes, we established a fixed effect of varying parameter panel model, examined panel data variables by the stationary test and cointegration tests, and estimated the model parameters of the regression estimation based on the general form of the C-D production function. On that basis, the effect of agricultural scientific and technological progress on the regional agricultural economic growth was analyzed by empirical analysis in complete detail. Through the analysis on the relevant elements of the contribution rate, it could better explain the impact mechanism of agricultural science and technology on regional agricultural economic growth. The results showed that there was significant difference in the contribution rate of agricultural science and technology in different regions, which indicated that the level of development of agricultural science and technology in China was uneven in different regions. The role of scientific and technological progress in agriculture in the process of economic growth in Chinas agriculture is still relatively small, and the present situation that agricultural economic growth in China relies on traditional high input, high consumption, low output, low efficiency of the extensive growth mode has not fundamentally changed.
