当今世界经济竞争十分激烈，在这种大背景之下经济高质量发展成为我国经济发展 的必然选择和现实要求。而科技创新作为带动发展的强大动力，为推动经济高质量发展 注入了许多新的动能。但目前仍存在许多问题。一方面，我国科技创新方面更多的是国 外引进，而自主创新较少，缺少基础性、原创性；另一方面，科技创新投资时期长且具 有较大的风险，企业往往很难仅靠内部力量去提升科技创新水平，需要政府的支持。而 财政投入作为政府发挥作用的主要渠道之一，可以通过促进科技创新、设施建设、基础 教等方面的发展来促进经济的发展。然而，财政投入的影响大小如何还需要进一步验证。 为此，本文构建指标评价体系测算科技创新和经济高质量发展水平，并基于测算出的指 数构建空间计量模型分析它们之间的相关性。最后，本文还引入了门槛回归模型来探讨 不同财政投入水平下科技创新对经济高质量发展的影响。结论如下： （1）我国地区发展极不平衡，东部地区的经济发展水平相对较高，中西部地区相对 较低。这种不平衡的发展状况在很大程度上阻碍了全国的经济发展和社会进步。为此， 我们应该通过加大对中西部地区的资金投入，提高教育水平等措施来实现全国经济的协 调发展和社会的全面进步。 （2）研究表明，科技创新是推动经济高质量发展的重要因素之一。科技创新可以提 高生产效率、降低成本、改善产品质量，从而增强企业的竞争力和市场占有率。同时， 也可以带来新的产业和就业机会。而政府可以通过财政投入来促进消费和投资，拉动经 济增长。然而，单纯的科技创新或财政投入并不能达到最好的效果，二者需要协同作用 才能更好地促进经济高质量发展。科技创新需要财政投入的支持，而财政投入也需要科 技创新的引领。只有二者相互配合，才能实现经济高质量发展的目标。 （3）我国经济高质量发展存在空间溢出效应，本地区的经济高质量发展不仅受本 地区的活动影响，还会受周边地区的活动影响。科技创新对相邻地区经济发展产生作用 不明显，但财政投入对相邻地区经济高质量发展存在负效应。 （4）财政投入对科技创新驱动经济高质量发展中存在双门槛效应。当财政投入水 平处于 0.150 到 0.309 之间时，科技创新对经济高质量发展促进作用更大。

Given the fierce economic competition in today's world, improving the quality of the economy has become an inevitable and essential choice for China's economic development. Science and technology innovation, as a powerful driving force, plays a crucial role in promoting economic growth and development, has brought a lot of new dynamism to promote quality economic development. However, there are still many problems. On the one hand, China's science and technology innovation is more imported from abroad, but less independent innovation, lack of basic, original; on the other hand, science and technology innovation itself has a long investment cycle, risky and other characteristics, It is difficult to break through the bottleneck in S&T innovation by relying entirely on businesses themselves, which is why S&T innovation needs government support. As one of the main channels for the government to play its role, financial investment can impact the development of the regional economy in numerous ways. In this new era, financial investment will certainly have an impact on the level of quality economic development, but the magnitude of the impact needs to be further verified. To this end, this paper provides an empirical analysis of the correlation between the degree of scientific and technological innovation and the fiscal contribution to the high-quality development of the regional economy. First, based on the existing literature, this paper develops a scoring framework for S&T innovation and economic quality development indicators respectively and assesses the level of S&T innovation and economic quality development in 30 provinces between 2010 and 2020.Subsequently, a spatial econometric model was constructed based on the measured indices of various variables, and regional panel countries were selected to conduct an empirical analysis of the influence of S&T innovation and financial investment on the quality of the regional economy and the spillover effects of spatial development, while examining the spatial correlation of each factor. Finally, a panel-threshold model was introduced to investigate the non-linear impact of S&T innovation on the economy's quality, considering different levels of fiscal inputs. The study's findings are as follows. (1) China's regional development is extremely uneven, with higher development levels in the eastern regions and lower levels in the central and western regions. (2) Both S&T innovation and fiscal investment can contribute significantly to the development of a quality economy, and the synergy between S&T innovation and fiscal investment can also contribute significantly to the development of a quality economy.This indicates that there is a certain link between science and technology innovation and fiscal investment in influencing economic quality development, and the combined effect of these two factors on economic quality is better than the combined effect of both factors on economic quality the two alone on economic quality development. (3) The positive spatial spillover effect of innovation and financial investment in science and technology on high-quality economic development implies that the development of a region's economy is not only influenced by its own performance but also by the performance of neighboring regions.S&T innovation has a negligible impact on the economic development of neighbouring regions, while financial investment has a negative impact on the quality of economic development of neighbouring regions. (4) The tax threshold has a dual impact on the quality of economic development associated with scientific and technological innovation. When the fiscal contribution falls between 0.150 and 0.309, S&T innovation plays a more important role in promoting quality economic development.
