Food Policy | 中国的区域农业生产力是否趋同：如何以及为何？【转】
摘要谷歌简单翻译（请以英文为准）：
本文测试了融合到单一全要素生产率（TFP）水平的假设，以及中国农业部门TFP增长率的稳定状态。根据多边TFP估计，我们发现中国农业部门近年来已经从2005 - 2007年期间TFP增长放缓中反弹。虽然收敛性测试结果证实了“追赶”效应，即TFP水平较低的省份往往比其他省份增长更快，但β收敛的估计率取决于我们如何捕捉跨区域的异质性效应。在不同的模型规格下，β收敛率在0.016到0.039之间。估计表明，教育程度，研发和中间商品密度（每单位劳动力）的较高增长率可以提高TFP增长。不幸的是，没有证据表明整体σ收敛，表明除了南部地区外TFP水平没有收敛。这意味着要赶上领先的省份，需要通过增加针对特定地区的研究投资，促进农村教育实现和加强体现的技术变革来为那些落后的人做出额外的努力。
This article tests the hypotheses of convergence to a single level of total factor productivity (TFP), and a steady state of TFP growth rate in China’s agricultural sector. Based on multilateral TFP estimates we found that China’s agricultural sector has rebounded in recent years from a slower TFP growth in the 2005–2007 period. While convergence test results confirm a “catch-up” effect that provinces with lower TFP levels tend to grow faster than others, estimated rates of β convergence are conditional on how we capture the heterogeneity effect across regions. The rates of β convergence range from 0.016 to 0.039 under different model specifications. Estimates show that higher growth rates of educational attainment, R&D, and intermediate goods density (per unit of labor) can enhance TFP growth. Unfortunately, there is no evidence of an overall σ convergence, indicating that TFP levels are not converging except in the South region. It implies that to catch up with leading provinces, it would require extra efforts for those lagging behind by increasing their region-specific research investment, promoting rural educational attainment, and enhancing embodied technical change.
