Empirical study on patent output and economic benefits in China's wireless communication industry

Abstract Based on patent applications and sales volumes of Huawei Company between 2005 and 2012, the paper conducts the correlation analysis of patents and economic benefits via regression methods. The research results show that there is the significant and positive linear correlation (P = 0. 000) between patents and sales in Huawei Company, and its regression curve is Y = 11748.380 +3.185 X (r = 0.983). There is the significant positive linear correlation (P = 0. 001) between R&D investment and patents in Huawei Company, and the regression analysis curve is Y = 13887.517 +1.639 X (r = 0.930). So more R&D investment leads to more patents, and intellectual property has the direct and important impact on company's future economic benefits. The corresponding intellectual property strategies should be given and carried in Chinese enterprises.
