Abstract: Using the method of DEA(Data-Envelopment Analysis), the paper measures the agriculture index of technical change and index of efficiency change of 28 provinces in China in the period 1995-2011. Then studied the impacts of agricultural Using the method of DEA(Data-Envelopment Analysis), the paper measures the agriculture index of technical change and index of efficiency change of 28 provinces in China in the period 1995-2011. Then studied the impacts of agricultural technological progress and efficiency improvement on the agricultural export trade of different regions in China in a unified economic model and assessed the mechanism of impacts. The result shows that the agricultural technological progress and efficiency improvement have played positive role on the export of agriculture among different regions in China and the eastern region of China is best obvious.The conduction mechanism showed a certain regional diversity: the eastern region’s economies of scale is weakened and urgently need to seek for transformation from agricultural scale expanding to quality improving; while the middle and western region are in the rising stage of economies of scale and still rely on innovation of science and technology further to expand agricultural exporting scale. In addition, effects of resource reallocation shows that the production technology is incompatible with its factor endowments.

摘要: 本文首先运用非参数Malmquist指数法测度1995~2011年期间我国东、中、西部地区的农业技术进步指数和技术效率指数。然后通过构建农产品出口贸易与技术进步、技术效率关系的计量模型,实证评析技术进步、技术效率对不同地区农产品出口贸易的影响和影响机制。实证结果表明,中国各区域的农业技术进步和效率改进对农业出口贸易有正向促进作用,其中,东部地区最为明显;而影响机制则表现出一定的地区差异性,东部地区的规模经济效应日益削弱,亟须寻求由追求农产品出口规模向提升农产品质量转变的途径;中部和西部则处于规模经济效应上升阶段,需进一步扩大经营规模。此外,要素重置效应表明,当前各地区农产品出口的生产技术与要素禀赋存在一定偏离。
