中文摘要：	创新是引领发展的第一动力，科技创新则是企业的立身之本。高新技术企业作为重要的创新主体，能够发挥较大创新带动作用。然而，当前高新技术企业面临的不仅是来自于市场的竞争压力，还有资金匮乏、公共产品溢出等问题，一定程度上需要政府给予相关补助才能具备发展创新能力的良好条件。但是，对于政府来说，给予高新技术企业多少补助最合适？政府补助对高新技术企业创新能力发展的作用如何？政府补助对于不同产权和不同行业的高新技术企业有何差异化影响？这仍然缺乏量化的、深入的研究以及权威的研究成果。 因此，为探讨上述问题，本文从政府补助的门槛效应实证展开研究。首先基于政府补助对高新技术企业创新能力门槛效应的理论分析，本文提出3个研究假设。其次，本文利用2015-2019年中国A股上市高新技术企业的全部样本数据，采用面板门槛模型实证检验了全样本下政府补助对高新技术企业创新能力的门槛效应。最后，分别基于产权差异和行业差异的视角，继续采用面板门槛模型探讨了政府补助对高新技术企业的异质性影响。 通过实证分析，得出以下结论：（1）整体来看，政府补助对高新技术企业创新能力的影响作用近似倒“V”型，对企业创新能力发展最适合的政府补助强度区间是该企业营业收入的0.2%以内。（2）基于产权性质来看，政府补助对国有高新技术企业创新能力影响作用为倒“V”型，最适合的政府补助区间为该企业营业收入的0.17%以内；对非国有高新技术企业创新能力存在双重门槛效应，最适合的政府补助区间为该企业营业收入的0.25%以内。（3）基于行业性质来看，政府补助对制造业高新技术企业创新能力影响作用呈现近似倒“V”型，最合适的政府补助区间为该企业营业收入的0.2%以内；对非制造业高新技术企业的影响不存在门槛效应。
英文摘要：	Innovation is the first driving force for development, and technological innovation is the foundation of an enterprise. As the important innovation subject, high-tech enterprises can play a greater role in driving innovation. However, at present, high-tech enterprises are not only facing competition pressure from the market, but also having problems such as lack of funds and overflow of public goods. Therefore, they need relevant subsidies from the government to have good conditions for developing innovation capabilities. For the government, what is the most suitable range of subsidies for high-tech enterprises? What is the role of government subsidies in the development of innovation capabilities of high-tech enterprises? How do different property rights and different industries affect the effect of government subsidies on high-tech enterprises? These issues remain to be studied. Therefore, in order to explore the above problems, this dissertation conducts an empirical study on the threshold effect of government subsidies. Firstly, based on the mechanism analysis of the influence of government subsidies on the innovation ability of high-tech enterprises, this dissertation proposes three research hypotheses. Secondly, this dissertation collects all the sample data of China's A-share listed high-tech enterprises from 2015 to 2019, and studies the threshold effect of government subsidies on the innovation ability of high-tech enterprises through the panel threshold model. Finally, this dissertation explores the heterogeneous impact of government subsidies on high-tech enterprises from the perspectives of property rights and industries, by the panel threshold model. Through empirical analysis, the following conclusions are drawn: (1) Overall, the impact of government subsidies on the innovation capability of high-tech enterprises is similar to an inverted "V" shape, and the most suitable government subsidy intensity range for the development of enterprise innovation capability is 0%-0.2% of business income. (2) Based on the nature of property rights, the effect of government subsidies on the innovation ability of state-owned high-tech enterprises is an inverted "V" shape, and the most suitable range of government subsidies is 0%-0.17% of business income; there is a double threshold effect on the innovation ability of non-state-owned high-tech enterprises, the most suitable government subsidy range is 0% to 0.25% of business income. (3) Based on the nature of the industry, the effect of government subsidies on the innovation capability of manufacturing high-tech enterprises presents an approximate inverted "V" shape, and the most suitable range of government subsidies is 0%-0.2% of business income; There is no threshold effect on the impact of non-manufacturing high-tech enterprises.
