摘要：本文回顾了改革开放四十年来我国农业生产率的收敛与赶超情况，并对未来趋势进行展望。本文利用模型平均法，同时考虑四种生产率测算模型，从而更好地考虑地区差异以及生产率的非线性变化趋势。本文随后利用三种收敛性检验方法评估我国农业生产率的收敛性，并探索加速农业生产率收敛的实现机制。基于省级、县级和各农产品层面的数据，本文的主要发现是：1）我国总体农业生产率并未实现收敛；2）重点研究的28省中有23省未实现省内农业生产率收敛；3）重点研究的23种主要农产品中有19种未实现生产率收敛；4）加强基础设施（灌溉）、提高教育水平、增加涉农财政支出和加速产业结构转型是未来加速实现我国农业生产率收敛的重要途径。

Abstract：This article investigates the progress and prospects of agricultural productivity catch-up in China since the rural reform. A model averaging method is employed to jointly consider four productivity estimates, which can better capture the province-specific and non-linear trend of productivity that was estimated with bias in previous literature. This article then utilizes three convergence tests to evaluate whether convergence has occurred and explores channels through which agricultural convergence can be achieved or accelerated. Using three panels at the province, county and commodity levels, this article concludes that agriculture is not on the right track to catch-up, since 23 out of 28 provinces and 19 out of 23 farm commodities fail to converge. However, the productivity gap may diminish in the future if the irrigation, education, public expenditure and structural transformation for lagging provinces can be improved.
