地级市创新能力影响因素的分层线性模型研究

Research on Hierarchical Linear Model of Influencing Factors of Innovative Ability of Prefecture-level City

摘要:

本文以2018年全国30个省份及其对应的280个地级市为研究对象,利用分层线性模型分析了省域层面、地级市层面的因素以及二者的交互作用对地级市创新能力的影响。结果显示,全国地级市创新能力的差异中有57.6%可以由省域层面的影响因素解释；地级市自身的经济水平、产业结构、R D经费支出可以提升其创新能力；省域层面的财政科技支出对其下辖地级市创新能力有正向影响,其他省域层面因素与地级市层面因素存在交互效应。

Abstract:

This article takes 30 provinces and their corresponding 280 prefecture-level cities in 2018 as the research object, and uses a hierarchical linear model to analyze factors at the provincial level, prefecture-level city level, and the interaction between the two on prefecture-level cities. The impact of innovation ability. The results show that 57.6% of the difference in innovation ability of prefecture-level cities across the country can be explained by influencing factors at the provincial level; the economic level, industrial structure, and R D expenditures of prefecture-level cities can improve their innovation capabilities; provincial level finance Science and technology expenditure has a positive impact on the innovation ability of prefecture-level cities under its jurisdiction, and other provincial-level factors and prefecture-level city-level factors have interactive effects.
