农业要素投入促进了农业经济增长？——来自中国30个省份的经验证据
Does Agricultural Factor Input Promote Agricultural Economic Growth?—Empirical Evidence from 30 Provinces in China

借鉴新古典经济增长理论，基于中国大陆地区30个省份1998~2018年的面板数据，利用固定效应回归模型，实证分析了农业生产要素投入作用于农业经济增长的路径机理。实证分析结果表明：全国层面看，有效灌溉面积、化肥、农业机械化要素投入对农业经济增长具有显著的正效应，劳动力、土地要素投入对农业经济增长具有显著的负效应，但不同省域地区之间的要素投入效果具有显著的异质性；各类生产要素的投入对农业经济增长的效应具有典型的历史性和时间性。基于此，提出了政府要从优化生产要素投入发力进而促进我国农业经济增长的对策和建议。
Using the neoclassical economic growth theory for reference, based on panel data of 30 provinces in the mainland of China from 1998 to 2018, using the fixed effect regression model, this paper empirically analyzes the path mechanism of agricultural production factor input on agricultural economic growth. The empirical analysis results show that: From the national level, the effective irrigation area, chemical fertilizer and agricultural mechanization factor input have significantly positive effects on agricultural economic growth, while the labor force and land factor input have significantly negative effects on agricultural economic growth, but the factor input effects between different provinces and regions have significant heterogeneity; the effects of inputs of various production factors on agricultural economic growth are typically historic and timely. Based on this, the paper puts forward the countermeasures and suggestions that the government should optimize the input of production factors to promote the agricultural economic growth in China.
