本地服务要素供给与高技术产业出口——来自中国省际细分高技术行业的证据

The Supply of Local Service Factor and Exports in High Technology Industry——Based on Provincial Data from China's High Technology Industries

本文利用中国30个省份2002、2007和2012年共计90张投入产出表测算了高技术行业使用的本地服务品含量,并在2000—2014年中国省级细分行业面板数据的基础上分析了本地服务要素供给对下游高技术产业出口二元边际的影响。研究结果表明:整体上,本地服务要素供给与中国高技术产业出口呈现U型关系,即随着本地服务要素投入的增加,高技术产业出口额呈现出先下降后上升的关系;并且该关系主要体现在对扩展边际的提升上。在控制内生性之后,这一结论仍然成立。细分行业上,生产性服务要素、消费性服务要素和公共服务要素都可以促进高技术产业的出口;其中,生产性服务要素和消费性服务要素对高技术产业出口的促进作用主要体现在对扩展边际的影响。本文的研究不仅较好地解释了后金融危机时代中国高技术产业出口快速增长的原因,更为产业升级提供了新的视角。

This paper estimates the local service that used in exports of high technology industries by 90 input-output tables of 2002, 2007 and 2012 in 30 provinces. And based on the panel data of provincial subdivision industry from 2000 to 2014, it analyzes the effect of local service inputs on dual margin of export in high technology industries downstream empirically. The results indicate that there is U-shaped relationship between the local service inputs and export in high technology industry overall, that is to say, with increase of local service inputs, volume of exports in high technology industries falls down at first and then raises up. In addition, the relationship has mainly embodied in ascension of extensive margin. After control of endogeneity, this conclusion has still established. Producer service elements, consumer service elements and public service elements can promote the export of high technology industries, and the promoting effect is also reflected in extensive margin. Research of this paper not only explains the cause of rapid growth of exports of China＇s high technology industry in the era after financial crisis, but also provides a new perspective of industrial upgrade.
