本文通过构建ECI指数对东、中、西部地区的出口竞争力进行了衡量和比较,并对FDI在各地出口竞争力的变动过程中所发挥的作用进行了研究。实证结果表明,外资的进入有力地提升了东部地区的出口竞争力,但并未对西部地区产生显著影响,在中部地区甚至产生了一定的负面作用。文章最后据此提出了相关的政策建议。 In this paper, we construct the ECI index to measure and compare the export competitiveness of the eastern, central and western regions and study the role of FDI in the changes of export competitiveness across the country. The empirical results show that the entry of foreign capital has effectively promoted the export competitiveness of the eastern region but has not had a significant impact on the western region and even had some negative effects in the central region. The article concludes with the relevant policy recommendations.
