Empirical Study on the Impact of New-Quality Productivity on Regional Economic Development in China

Abstract

New-quality productivity (NQP) reflects the modernization of productivity, characterized by higher technological levels, better quality, and greater efficiency and sustainability. Against the backdrop of technological innovation, NQP plays an increasingly significant role in economic development. Sustained growth of NQP is key to maintaining stable and rapid economic progress. This paper adopts the new-quality productivity index developed by scholar Lu Jiang, Guo Ziang and Wang Yuping, which comprises three dimensions, including innovation capacity, technological research and development, and production efficiency. By using this index, an OLS regression analysis is conducted on the economic development levels of various regions. Through regression analysis, the paper examines the impact of these indicators on regional economic development and provides relevant policy recommendations. The results show with a higher new-quality productivity index tend to have a higher level of economic development. Theoretically, this result further illustrates that new-quality productivity enhances production efficiency through technological innovation and resource optimization, thereby driving economic growth. New-quality productivity not only transcends the traditional factor-driven growth model but also injects stronger innovative momentum and potential for sustainable development into regional economies. On a practical level, improving the level of new-quality productivity can effectively promote the rational allocation of resources, accelerate industrial structure upgrades, and significantly enhance the affluence and vitality of regional economies.
