A Quantile Regression Analysis on the Correlation between Independent Innovation and Exports of High-tech Products in China

The purpose of this paper is to analyze the correlation between independent innovation and exports of high-tech products by constructing a research framework including domestic and foreign patent applications accepted. Quantile regression is applied to empirical study the impacts of independent innovation to exports of high-tech products from 1986 to 2009 in China. The results show that medium and low level independent innovation has positive effects to exports of high-tech products at various kinds of conditional distribution, but the role of high level independent innovation to exports of high-tech products is insignificant. The high level international technology spillovers play significant positive effects for exports of high-tech products at various kinds of conditional distribution, while the effects of medium and low level international technology spillovers to exports of high-tech products is insignificant. Empirical results suggest that policy must be formulated to support domestic high level independent innovation.
