摘    要:农业增长离不开生产要素投入的增加和农村基础设施的完善。由于农村基础设施具有技术不可分性、低排他性、不可贸易性等特征,因而应当主要由政府的公共投资来提供。运用1994—2009年期间中国各省、市、自治区的面板数据,通过模型的比较分析,发现耕地投入和农业劳动力投入是不断递减的,但由于农业经营制度变革、公共投资增多、农业技术进步导致劳动生产率提高等原因,农业总产值仍稳步提升。农田水利灌溉、农业科研、农村教育和农村电力等方面的公共投资都能推动农业增长,但由于各项投资的边际影响不同,需要在不同地区有所侧重。研究还发现,农村基础设施公共投资能够明显缩小西部地区与中东部地区的农业发展差距,促进区域经济协调可持续发展。

关 键 词:农村基础设施  公共投资  农业增长

Abstract:Agricultural growth is indispensable to production factor input and perfection of rural infrastructure.Because of the characteristics of technological indivisibility,low-exclusive,non-trade,agricultural infrastructure should be provided mainly by the Government’s public investment.Using panel data of all provinces in China from 1994 to 2009,we conducted a comparative analysis on two models and found the input of cultivated land and agricultural labor input was constantly decreasing.However,due to agricultural management system reform,increased public investment,agricultural technological progress and other reasons,the gross output value of agriculture is steadily improving.Public investment in irrigation,agricultural research,rural education and rural electric power and other aspects can promote agricultural growth.Because the marginal impact of investment is different,so it should be differentiated in different regions.We also found that public investment in rural infrastructure can significantly reduce agricultural development gap in the Western region and Eastern region,promoting regional economic coordination and sustainable development.
Keywords:Rural infrastructure  Public investment  Agricultural growth  Cross-province panel data
