摘　　要：分析经济产业结构影响因素对扩大电炉企业生产规模、重构电炉生产经济产业结构有着十分重要的现实意义,因此基于混合回归模型,分析了电炉生产企业经济产业结构影响因素。分析电炉生产规模现状,根据现阶段电炉国际贸易格局,选择四项指标构建混合回归模型。将我国电炉进口规模、电炉交通运输能力、电炉生产技术创新和环境规制作为自变量,电炉生产规模作为因变量带入混合回归模型中,实现电炉生产企业经济产业结构影响因素的深入分析。分析结果表明,我国电炉进口规模与电炉生产存在负相关联系,电炉交通运输能力、电炉生产技术创新和环境规制强度与电炉生产存在正相关联系。根据分析结果,可以优化经济产业结构,扩大生产规模,推动电炉生产发展。Analyzing the influencing factors of economic industrial structure is of great practical significance for expanding the production scale of electric furnace enterprises and reconstructing the economic industrial structure of electric furnace production. Therefore, based on a mixed regression model, the influencing factors of economic industrial structure of electric furnace production enterprises were analyzed. Analyze the current production scale of electric furnaces, select four indicators based on the current international trade pattern of electric furnaces, and construct a mixed regression model. Taking the import scale of electric furnaces, transportation capacity of electric furnaces, technological innovation in electric furnace production, and environmental regulations in China as independent variables, and the production scale of electric furnaces as the dependent variable, a mixed regression model is introduced to achieve in-depth analysis of the factors affecting the economic and industrial structure of electric furnace production enterprises. The analysis results indicate that there is a negative correlation between the import scale of electric furnaces in China and electric furnace production, while there is a positive correlation between electric furnace transportation capacity, electric furnace production technology innovation, and environmental regulation intensity and electric furnace production. According to the analysis results, it is possible to optimize the economic and industrial structure, expand production scale, and promote the development of electric furnace production.
