IMPACTS OF NEW QUALITY PRODUCTIVITY ON TECHNICAL ADVANCES IN WESTERN CHINA BASED ON SPATIAL DURBIN MODEL

doi:10.13776/j.cnki.resourcesindustries.20250702.004

Abstract

Abstract: This paper uses spatial Durbin model and 1990 to 2022 panel data of Western China's 84 prefectures to study the impacts of new quality productivity on technical advances in western China. There is an upside-down “U-shaped” relation between urban sizes and technical advances, and the urban sizes have yet reached the turning point. That's means appropriately expanding urban sizes play a positive role in western China's technical advances. Direct effects of population density, economic quality and house price/income ratio and educational expense are positive and outstanding, indirect effects of economic quality, foreign direct investment and educational expense are positive and outstanding, the total effects of economic quality, foreign direct investment and educational expense are positive and outstanding, of which economic quality and educational expense play a positive promotion on technical advances in the local prefecture, its neighboring cities and even the whole area, educational expense plays the most. Direct effects of residential savings are negative and outstanding, indirect effects of population density, residential savings, house price/income ratio and inflation ratio are negative and outstanding, the total effects of residential savings, house price/income ratio and inflation ratio are negative and outstanding, of which direct, indirect and total effects of residential savings are negative, a key factor in blocking technical advances in western China. This paper presents suggestions on appropriately enlarging urban sizes, increasing educational expense, raising economic quality, attracting foreign direct investment, encouraging residential consumption to the promotion of new quality productivity on technical advances, which is significant to realizes technical power and to boost economy in western China.

Key words: new quality productivity, western China, spatial aggregation, technical advances

摘要： 论文基于空间杜宾模型，利用1990—2022年中国西部地区84个地级及以上城市面板数据，探讨新质生产力对中国西部地区技术进步的影响。研究结果显示：1）西部地区城市规模与技术进步存在倒“U”型曲线关系，目前西部地区城市规模尚未达到拐点，城市规模扩大对技术进步仍存在正向促进作用；2）人口密度、经济发展质量、房价收入比和教育支出对西部地区技术进步的直接效应为正且显著，经济发展质量、外国直接投资和教育支出对西部地区技术进步的间接效应为正且显著，经济发展质量、外国直接投资和教育支出对西部地区技术进步的总效应为正且显著，其中经济发展质量和教育支出对本市、邻市乃至整个地区的技术进步指数均有正向促进作用，且教育支出对技术进步的正向促进作用最强；3）居民储蓄对西部地区技术进步的直接效应为负且显著，人口密度、居民储蓄、房价收入比、通货膨胀率对西部地区技术进步的间接效应为负且显著，居民储蓄、房价收入比、通货膨胀率对技术进步的总效应为负且显著，其中居民储蓄对技术进步的直接效应、间接效应和总效应皆为负，是抑制西部地区技术进步的关键因素。因此建议中国西部地区应通过适度扩大城市规模、加大教育支出、提高经济发展质量、吸引外国直接投资、刺激居民消费等措施，充分发挥新质生产力对技术进步的促进作用。这对于实现科技强国、促进西部地区社会经济全面振兴具有重要的现实意义。
