中国蔬菜出口增长的二元边际分析

基于2004—2011年中国蔬菜产品HS-6位出口数据,运用二元边际分解方法对中国蔬菜出口增长进行实证分析。研究结果显示,中国蔬菜出口增长主要来自于扩展边际的贡献,但集约边际在对主要贸易伙伴的出口中也发挥着重要作用。对集约边际进一步分解后发现,中国蔬菜出口增长主要来自于数量扩张,价格边际的贡献相对较小。蔬菜出口企业应在保持蔬菜品种多样化的同时尽量开发技术含量高、附加值较高的蔬菜新产品,以实现中国蔬菜出口增长模式的转变。

Dual Margin Analysis of Chinese Vegetable Export Growth

Decomposition methodology is used to do an empirical analysis for export growth of Chinese vegetable based on HS-6 export data of Chinese vegetable products during the period 2004—2011. The result shows that although the growth of China＇s export mainly depends on extensive margin,intensive margin plays an important role in the export to major trade partners. By decomposing the intensive margin deeply,it is found that Chinese vegetable export growth mainly comes from quantity expansion,contribution of price margin is relatively tiny. To change the export growth mode of Chinese vegetable,enterprises should try their best to keep the variety of vegetable products and develop new products with high technological content and value.
