Research On The Influence Of Preferential Policies Of Enterprise Income Tax On The Innovation Of Communication Equipment Manufacturing Enterprises

In recent years,China's economic growth rate has gradually slowed down.The report of the 19 th national congress pointed out that China's economic development has changed from the previous stage of high-speed growth to the stage of high-quality development.At present,countries all over the world pay more and more attention to technological competition,and technological innovation has become the core competitiveness in the fierce competition.China has always attached great importance to the development of technological innovation and put innovation driven development strategy at the core of national development.However,due to the late start of China's development,there is still a large gap between China and developed countries in terms of overall technological innovation.Especially in some key technologies,they are not only behind the western developed countries,but also facing the technical blockade of western countries.Therefore,only by focusing on technological innovation,strengthening independent research and development,and improving the overall innovation capacity of the country can we catch up with or even surpass the developed countries in key technology fields.With the birth of the fifth generation communication technology,the new generation communication technology and market has become the focus of competition between governments and communication enterprises.In order to crack down on the development of China's communication equipment manufacturers,the U.S.government has even launched serious economic sanctions against ZTE and Huawei.Faced with the comprehensive sanctions of the U.S.government,Huawei,the leader of China's communication equipment manufacturing industry,has not been seriously affected,but has received 5g commercial contracts from many western developed countries.The reason why Huawei is continuously recognized by western countries lies in that Huawei adheres to independent technology innovation and high R&D investment for many years in a row to become the industry leader of 5g technology.However,the R&D innovation of enterprises generally has the characteristics of high investment and high risk.The situation of "market failure" is easy to occur simply depending on the spontaneous allocation of innovation resources by the market,which leads to the serious phenomenon of "free riding",thus affectingthe enthusiasm of enterprises for innovation.Therefore,it has become a common practice for governments to encourage enterprises to increase R&D innovation and enhance the innovation ability of domestic enterprises by means of preferential tax policies.Firstly,based on the theory of market failure and endogenous economic growth,combined with the transmission mechanism of tax preferential policies on R&D innovation of enterprises,this paper analyzes the impact of income tax preferential policies on innovation of communication equipment manufacturing enterprises in China.Secondly,by analyzing the current preferential tax policies on enterprise innovation in China and comparing them with those in western developed countries,this paper points out the shortcomings of the preferential tax policies in China.Finally,through the establishment of data model,the data regression analysis of 94 domestic A-share listed communication equipment manufacturing enterprises in 2014-2018 shows that there is a positive correlation between China's current income tax preferential policies and the R&D innovation input of communication equipment manufacturing enterprises,but the relationship between the preferential policies and the innovation output of communication equipment manufacturing enterprises is not obvious,and based on the experience of foreign countries,the paper puts forward the following conclusions One step to improve our current tax preferential policies.
