| Abstract: | This paper empirically analyzes the relationship between invention patents,utility model patents,design patents and enterprises’ financial performance,with the help of econometric theories related to cointegration and Granger causality analysis.The results show that there are long-term equilibriums between invention patents,utility model patents,design patents and enterprises’ prime operating revenues.Besides,invention patents and utility model patents are the Granger cause of enterprises’ prime operating revenues,while,between design patents and enterprises’ prime operating revenues,there are Granger causes with each other.What is more,it is the design patent that is making the maximum contribution to the enterprises’ prime operating revenues. |
