碳排放约束下河南省农业全要素生产率增长与分解

传统的农业全要素生产率测算方法很少兼顾环境约束，因而无法反映出农业经济增长的真实绩效。文章采用Malmquist Luenberger指数分析了2000-2012年碳排放约束下河南省18个地市的农业全要素生产率及其分解成分。研究结果表明，碳排放约束下河南省农业全要素生产率呈增长趋势，但表现出较大的波动性，其动力主要来源于技术进步；分地区来看，河南省各地市之间农业全要素生产率差异显著，其中，豫北地区农业全要素生产率增长最高。

Growth and decomposition of agricultural total factor productivity in Henan Province under carbon emissions constraint#br#

 Past studies regarding agricultural total factor productivity measurement mostly focused on traditional inputs， and rarely took environmental factors into consideration. Therefore， it is unable to reflect the real growth performance of agriculture. Using the Malmquist Luenberger productivity index method， the present paper analysed the growth and decomposition of agricultural total factor productivity in Henan Province from 2000 to 2012 under carbon emissions constraint. It was shown that the agricultural total factor productivity in Henan Province increased consistently under carbon emissions constraint， but the increase rate exhibited great volatility. The increase was mainly driven by the advances of agricultural technologies. The growth of agricultural total factor productivity showed significant differences among 18 cities in Henan Province. In general， it was the highest in the North Henan.
