摘　　要：本文运用非参数Malmquist指数法测度1995-2011年间我国东、中、西部地区的农业技术进步指数和技术效率指数,通过构建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及其传导机制。研究结果表明,中国各区域的农业技术进步和效率改进对农产品出口贸易有促进作用,而影响传导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出口质量转变的途径,中部和西部则处于规模经济效应上升阶段。此外,要素重置效应表明,当前各地区的农业生产技术与要素禀赋存在一定偏离。Using the method of DEA, the paper measures the agriculture index of technical change and index of efficiency change of 28 provinces in China, followed by a study on the impacts of agricultural technical and efficiency change on the agri- cultural export of different regions in China and assessment of the mechanism of the impacts. The result shows that the agricul- tural technological and efficiency improvement play positive role on the export of agriculture in China. The mechanism shows regional diversity： the east is declining in its economies of scale and urgently needs to seek transformation from agricultural scale expansion to quality improvement ; while the middle and west are in the rising stage of economies of scale and still rely on innovation of science and technology to further expand their agricultural exporting scale. In addition, effects of resource reallo- cation reveal certain incompatibility of the production technology with its factor endowments across different regions in China.
