沈阳装备制造业外商直接投资技术溢出效应实证研究

Empirical Study on FDI's Technology Spillover Effect on Equipment Manufacturing Industry in Shenyang

以柯布-道格拉斯生产函数为基础，构建了包括基本模型和扩展模型在内的数量模型，提出了相关研究假设．在此基础上，采用1999-2003年的行业数据，对沈阳装备制造业外商直接投资的技术溢出效应进行了实证研究．结果显示，外资直接投资对沈阳装备制造业产生了显著的技术溢出效应；同时发现，所选定的三个因素，即市场竞争、劳动力流动和行业开放度对溢出效果的影响都是积极的，这对有效利用外商直接投资、提高外商直接投资的技术溢出效应提供了重要的参考．

According to the Cobb-Douglas＇ production function, a quantity model was developed including a basic model and extension one with some assumptions given. To verify the assumptions, the technology spillover effect of foreign direct investment（FDI） on the equipment manufacturing industry in Shenyang was studied empirically with the relevant data from 1999 to 2003 taken as reference. The results showed that FDI has contributed greatly the technology spillover effect to the equipment manufacturing industry in Shenyang. All the three factors selected have obviously positive influence, i.e. the market competition, labor mobility, and the opening degree of industry. Such a conclusion is important and beneficial to taking advantage efficiently of FDI and improving its technology spillover effect.
