Can intellectual property rights protection and governmental R&D investment promote Chinese enterprises' R&D investment?

摘要

This paper establishes an impact factor model among government R&D input, enterprise R&D input and IPRP in China. It uses data from 1992 to 2012 for regression analysis and finds that government R&D input in enterprises, institutions and universities has a leverage effect on enterprise R&D input, although the leverage effect caused by government R&D input in universities is not prominent, and proper IPRP can promote Chinese enterprise R&D input. The further Granger causality test shows that IPRP produced structural changes in Chinese enterprise R&D input in approximately 2002, and its leverage effect reached 0.147, which is double the previous effect and exceeds the leverage effect caused by government R&D in institutions and in universities. The findings verify that IPRP is the source of power for promoting Chinese enterprises' technology innovation.
