The literature generally agrees with the close relationship between the level of economic and technological development, but there are different views on how to define and measure the level of technological development. The traditional theory holds that the relationship between capital and labor force is the dominant factor determining the level of technological development, while the technology gap theorists link innovation activities with the level of technological development. A high level of innovation activities means a higher per capita value-added level. The standards of measuring technology level and or innovation activities can be divided into technology input measures and technology output measures. This paper aims to explore the relationship between the number of patents owned by enterprises and marketing ability, including the relationship between the number of patents and enterprise income, the advantages and disadvantages of measuring patents for enterprise development, the advantages of multiple patents for enterprises, and the classification of patent dependent enterprises and non patent dependent enterprises.
