国农村发展研究院龚斌磊研究员独著论文“Interstate Competition in Agriculture: Cheer or Fear? Evidence from the United States and China (农业竞争是喜是忧?来自美国和中国的证据)”被农经国际TOP期刊《Food Policy》录用发表。《Food Policy》是SCI/SSCI双检索期刊,在农业经济JCR类别中排名第一,被浙大农经系认定为TOP期刊,2017年影响影子3.111,五年影响因子4.091。这是龚斌磊研究员本年度第九篇SSCI独著论文,其中Q1区论文七篇。

 

中美两国在国际农产品市场上扮演者举足轻重的角色,认识两国国内州(省)际竞争如何影响其农业生产至关重要。本文使用空间生产函数和模型平均法,旨在测算多维度州(省)际竞争对农业生产的多重影响。利用中美两国的农业年度面板数据,本文发现州际竞争在美国产生正向溢出效应并促进农业全要素生产率的提升,而省际竞争在中国产生负向溢出效应并遏制农业全要素生产率的增长。同时,美国州内农业竞争提高农业全要素生产率而中国省内竞争降低农业全要素生产率。此外,中美两国农业增长动力的差异也证明了美国农业市场化程度高于中国。美国农业工业化与市场化使其享受竞争带来的红利,更多是依靠其软实力发展农业。中国的计划经济特征和政府干预措施对农业发展有利有弊,其硬实力对农业发展的促进作用更为明显。基于实证结果,本文给出中美双方在农业发展方面可以彼此学习的关键点。

 

Abstract:Understanding how interstate competition affects agricultural production in the United States and China is important, as the international food market depends heavily on these two giants. This article aims to evaluate the overall effects of multi-dimensional interstate competitions on agricultural production, which is achieved using spatial production functions and model averaging methods. Using panel data, this article finds that interstate agricultural competition ought to be encouraged in the United States due to their positive impacts on spillovers and productivity but should be discouraged in China as it leads to negative spillovers and a decrease in productivity. Additionally, intrastate competition increases productivity in the United States but conversely decreases productivity in China. Other major drivers of productivity growth in the two countries are also found to vary, which provides evidence of a centrally planned system in China compared with the market system in the United States. U.S. agriculture enjoys the benefits of competition thanks to agricultural industrialization and a competitive market, while the planned system with government interference found in China has benefits as well as detriments. Food policy implications are also discussed.
