Abstract:Taking China and South Korea as an example, this paper makes a comparative study on the supporting policies of high-tech enterprises in China and South Korea from the perspective of policy tool mix. According to the three dimensions of supply side, environment side and demand side, this paper classifies six kinds of policies: financial aid, talent support, intellectual property protection, tax preference, government procurement and technology transformation incentive, and analyzes the main practices and similarities and differences of China and South Korea in the support policies of high-tech enterprises. It is found that the tax policies of China and South Korea both play an independent role, and there is a synergistic effect between different policy tools. There are differences in the starting point, logic, tool choice and policy content of the two countries' policies. On the basis of financial support and tax incentives, China focuses on the role of talent policy, while South Korea tends to promote the development of high-tech enterprises through technology transformation incentive and intellectual property protection. Finally, based on the research conclusions, the paper puts forward some countermeasures and suggestions. The author thinks the Chinese government should actively play a leading role in supporting policies for high-tech enterprises, improve incentives for enterprise innovation, and effectively promote the development of industry-university-research cooperations.
