创新水平对电信设备企业出口影响的实证研究

The Empirical Study on the Effect of the Innovation Level on the Export of Chinese Telecom Equipment Firms

本文使用中国电信设备企业的面板数据,首先运用固定效应模型与随机效应模型,实证检验了影响中国电信设备企业出口的因素。然后考虑到企业出口决定和出口量是两个相互联系的过程,我们采用Heckman两步选择模型进行估计发现:创新水平、人均工资、人均产出、以及宏观经济政策对中国电信设备企业的出口增加决定和出口增加都存在显著为正的影响。

This article uses the panel data of 1998-2007 of Chinese telecom equipment companies to examine the factors that affect the exports of Chinese telecom equipment companies. After using the fixed effects model and random effects model, this article utilizes Heckman two-step selection model to estimate in order to get more reliable results for taking into account two interrelated processes between the export decision and export volume. The results have shown that： the change in the level of innovation, per capita wage, per capita output and macroeconomic policies have a significant positive impact on the exports increase decision and exports increase of Chinese telecom equipment companies.
