马旺林:农业合作社有助于技术效率提升吗?基于苹果种植户的数据研究

2019年3月15日,北航经商院 • 经济学双周论坛迎来了2019年春季的第二十七期讲座。此次主讲特别邀请到了新西兰林肯大学讲师,博士生导师马旺林博士。他主要从事农业经济学和发展经济学方面的研究。此次报告题目是“农业合作社有助于技术效率提升吗?基于苹果种植户的数据研究”,分析加入农业合作社对果农苹果生产技术效率的影响。

研究结果表明:在控制不同程度的选择性偏误问题下(即同时控制由可观测因素和不客观性因素造成的选择性偏误,只考虑由可观测因素造成的选择性偏误,只考虑由不可观测因素造成的选择性偏误,不考虑任何选择性偏误),社员的平均效率值为79%~86%,而非社员的平均效率为74%~84%;参与合作社对社员果农的技术效率有实质性的提高。

现场20余名经管学院的老师和同学认真听取了报告, 并提出问题,共同探讨。论坛在热烈的学术氛围中圆满结束,我们期待下期经济学双周论坛的精彩学术碰撞。

 

Dr. Wanglin Ma: Agricultural Cooperatives andTechnical Efficiency of Apple Farmers in China

 

   On 15 Mar. 2019, we welcomed the speaker Dr. Wanglin Ma from Lincoln University, New Zealand. He is a lecturer and Ph.Ds upervisor. He works in the field of agricultural economics and developmenteconomics. In the seminar, Dr. Ma presented his last research “Agricultural Cooperatives and Technical Efficiency of Apple Farmers in China”, which examinesthe impact of agricultural cooperative membership on technical efficiency (TE)of apple farmers in China.

   The empirical results show that TE for cooperative members ranges from 79 to 86 percent and that for non-members ranges from 74 to 84 per cent, depending on how biases are controlled. In addition, the efficiency levels of both members andnon-members of cooperatives appear to be underestimated if the selectivity biasis not appropriately addressed. Our findings conclude that the average TE is consistently higher for cooperative members relative to their counterparts, highlighting the positive role of contemporary agricultural cooperatives inpromoting efficient usage of production inputs.  

   More than 20 teachers and students of the School of Economics and Management have participated in the seminar and discussed thestudy with Dr. Ma. We are looking forward to the Bi-Week Applied Economics Colloquium next week.
