外商直接投资对制造业技术效率的影响——以江苏省为例

The Influence of Foreign Direct Investment on the Technical Efficiency in Manufacturing Industry——Take Jiangsu Province as an Example

文章利用2004年—2009年江苏省制造业29个部门的面板数据,运用随机前沿分析(SFA)模型,估计江苏省制造业各部门的技术效率值以及FDI对其技术效率的影响。其结果表明,江苏省制造业各部门之间技术效率水平呈不平衡状态,最大值为石油加工、炼焦及核燃料加工业,其与最小值造纸及纸制品业相差0.5884;整体技术效率水平以年均1.65%的速度增长,一些部门也出现相似的趋势。FDI对江苏省制造业技术效率下降具有显著影响,FDI每增长1个百分点,技术效率降低0.1678个百分点。

By applying the model of Stochastic Frontier Analysis and the panel data of 29 departments in the manufacturing industry of Jiangsu Province during 2004-2009, this paper estimates their values of technical efficiency as well as the Influence of FDI on technical efficiency. The results indicate that there exists disequilibrium of technical efficiency in these departments. The interval reached 0.5884 between the maximum and minimum value, respectively found in the petroleum refinery, coking and nuclear fuel processing industry and the papermaking and paper products industry. The general level of technical efficiency was growing at a rate of 1.65% per year, while some departments showed similar trends. FDI has a profound effect on the declines of technical efficiency in the manufacturing industry of Jiangsu Province, given the fact that a 1% increase in FDI was associated with a 0.1678% drop in technical efficiency.
