金融支持上游度对高技术产品出口的影响研究

The effects of financial support upstreamness to high technology products export

基于WIOD投入产出数据,在修正Antràs等模型的基础上,测度出了34国1997-2011年金融支持上游度,并从整体和分时间段两个层面首次分析了金融支持上游度对高技术产品出口的影响机制。得到的结论主要有:首先金融支持上游度对高技术产品出口的作用机制呈现倒U型,中国金融支持上游度偏高,接近金融支持上游度对高技术产品出口作用的负效应门槛;其次契约型地理优势和毗邻大国型空间地理优势有助于促进一国高技术产品的出口,而沿海型空间地理优势则对高技术产品出口的作用不显著;最后经济发展水平提升、企业经营环境的改善和丰富的要素资源均能促进高技术产品的出口,但丰富的要素资源并非促进高技术产品出口的"长期稳定"因素,经济发展水平提升对高技术产品出口的边际正效应呈逐渐降低的趋势,而企业经营环境的改善对高技术产品出口的作用力则有所提升。

With the input - output data from WIOD, this paper estimates 34 countries＇ financial support upstreamness through properly revised Antras et al （2012）, then analysis the effects of financial support upstreamness to high technology products export from total and subsection level. The results show that ： firstly the effects of financial support upstreamness to high technology products export like inverse U, China＇s financial support upstreamness is too high, which is near the negative threshold ; Secondly institutional geographic advantage and being a neighbor of larger importing country do good to a country＇s high technology product export, the near sea geographic advantage doesn＇t have significant effects to high technology product export; Thirdly economic development ,business environment and natural resource have positive effects to the high technology product export, but the natural resource is not a＂ long dependable＂ factors, the impacts of economic development to high technology product export are declining, the impacts of business environment to high technology product export are becoming stronger.
