| 内容提要 | 本文在新古典资源禀赋理论框架下，通过利用社会网络分析工具和广义引力模型，考察了二元层面资源禀赋差异与体系层面结构因素对中国农产品贸易的影响。在Bergstrand广义引力模型的基础上，利用UN-Comtrade和CEPII 2007—2011年SITC—4位数中国农产品进出口贸易数据，借助泊松（PPML）家族准极大似然估计法，对资源禀赋差异和结构因素对农产品贸易的影响进行回归。研究发现：二元层面资源禀赋差异和体系层面结构因素对中国农产品贸易产生了显著影响。来自体系层面的结构对等性因素对资源禀赋差异产生了显著的“替代效应”，结构对等性因素的存在削弱了农产品贸易对资源禀赋差异的依赖；来自体系层面的角色对等性因素对资源禀赋差异产生了显著的“分层效应”，资源禀赋差异对农产品贸易的影响在贸易国为核心和非核心国家之间显著不同。 |
| Abstract | Using the social network analysis tool and the generalized gravity equation, this study investigates the effects of dyadic level differences in resource endowments and structural factors on the trade of agri-food products in China through Poisson family of ML estimation under the H-O framework, with the 2007-2011 SITC-4 digit trade data of agri-food products from UN-Comtrade and CEPII database. We find that the effects of differences in resource endowments and structural factors on the trade of agri-food products in China are significant. From structural equivalence factor, there is a significant “substitution effect” on the differences in resource endowments that the existence of structural equivalence lessens the dependence on differences in resource endowments. From role equivalence factor, there is a significant “stratification effect” of world-system status on resource endowments, the effects of resource endowments on agri-food product trade show a significant differences between core and noncore countries. |
