摘要
本文以创新理论和贸易理论为基础,运用面板数据模型分析了技术引进、自主创新对泛珠三角区域内九省区出口商品结构的影响,结果表明,当期的外资依存度不利于改善泛珠三角区域内九省区的出口商品结构,但滞后二期的外资依存度则产生正面作用;当期的专利授权量有助于优化泛珠三角区域内九省区的出口商品结构,但滞后一期的专利授权量则会产生负面影响;外资依存度与专利授权量的交叉项对泛珠三角区域内地九省区的出口商品结构能够产生正面影响。最后在实证基础上提出相关的政策建议。
Based on innovation theories and trade theories, the paper analyzed technology import and in- digenous innovation on the export commodity structure of nine provinces from Pan - Pearl River District in the Mainland using panel data model. The empirical results show that the impact of the current ratio of dependence on foreign trade on the export commodity structure of nine provinces from Pan - Pearl River District in the Mainland is negative, and the ratio of dependence on foreign trade of lag 2 level plays a positive influence. The effect of patents granted on the export commodity structure of nine provinces from Pan - Pearl River District in the Mainland is positive, patents granted of lag 1 level have a negative impact. The cross terms of ratio of dependence on foreign trade and patents granted have a positive impact on the export commodity structure of nine provinces from Pan -Pearl River District in the Mainland. Finally, the paper proposed relevant policy recommendations based on the empirical research.
