传统的农业全要素生产率测算方法很少统筹兼顾资源和环境约束,无法反映出我国农业经济增长的真实绩效。本文采用Malmquist-Luenberger指数将水资源和农业面源污染因素纳入传统的农业全要素生产率分析框架,测算分析了资源环境约束下中国1998-2009年30个省份的农业全要素生产率及其分解成分。研究结果表明:①是否考虑资源环境约束对农业全要素生产率的核算结果具有显著影响,并可能导致政策误判;②考虑资源环境约束的农业全要素生产率显著低于传统不考虑资源环境约束的测算结果,我国的农业经济呈现出以严重破坏生态环境和大量消耗资源为代价的粗放型增长;③资源环境约束下我国东部地区的农业全要素生产率高于中西部地区,中西部地区面临着农业增长与资源环境相协调的艰巨任务。
As an important indicator of agricultural growth performance,agricultural total factor productivity has attracted considerable attention.Agricultural total factor productivity measurement has mostly considered traditional inputs such as capital,labor and land,rarely taking resource and environmental factors into consideration.This is a biased evaluation and is unable to reflect the real growth performance of agriculture.Here,we apply the malmquist-luenberger productivity index to estimate agricultural total factor productivity accounting for water resource and agricultural non-point source pollution in China from 1998 to 2009.Fertilizer,animal,labor,machine,sown area and water consumption were considered as input indicators;provincial agricultural output value and agricultural non-point source pollution were considered as good output and bad output,respectively.We found that water resource and agricultural non-point source pollution had a significant influence on the measurement of agricultural total factor productivity growth.So it makes sense to take natural resources and agriculture environmental pollution into account when measuring agricultural productivity growth rates.Overall agricultural total factor productivity under the constraint of resource and environment is 1.029 and very low,implying that agricultural economic rapid growth is at the expense of natural resource destruction and agriculture environmental pollution in China.The agricultural total factor productivity incorporating water resource and agricultural non-point source pollution is different among provinces and municipalities.Provinces in Eastern China have higher agricultural total factor productivity,while provinces in Central and Western China have lower agricultural total factor productivity.The coordination task of agricultural economic growth and environmental protection and resourcesaving is arduous in Central and Western China.Our results indicate that the environmental pollution and resource destruction problem in China remain a seri
