南稻北麦、协作与信任的经验研究

Crops,Cooperation and Trust Pattern:Empirical Evidence from China

本文基于"南稻北麦"的种植格局,研究了农业种植方式对中国南北方信任模式的影响。利用CFPS等微观数据的研究表明,南方水稻区家庭与村庄内部更高的短半径协作需求诱发出亲友近邻间更高的受限制信任模式;北方小麦区为应对农忙期种植压力而诱致出的异地雇佣关系拓展了协作半径,进而发展出跨越血缘与地缘的一般性信任模式。进一步的工具变量估计和安慰剂检验支持了本文的研究结论。通过构建"父母—子女同住数据库",本文进一步验证了信任观念在代与代之间的"复制"与传承,这使得中国传统的农业种植方式持久地形塑了南北方的信任模式。

From the viewpoint of＂rice versus wheat agriculture＂,this paper investigates the effects of agricultural production of rice and wheat on different trust pattern between south and north area in China.By using the CFPS（2010）,the empirical results show that families who plant rice are more likely to form the Limited-Trust pattern through the channel of cooperation among their relatives and neighbors during rice production activities.Whereas families who plant wheat are more likely to form the Generalized-Trust pattern,because the constraint of harvest periods call for cross-regional employment relationship.This finding is robust to using instrumental variable estimation and placebo test.In order to examine the importance of trust pattern persistence,we construct the co-residing children-parents pairs and find that the long-term impacts of traditional agricultural production on cultural norms may due to the evolution of trust pattern from parents to children.
