基于Tobit模型的光伏产业影响因素实证分析

Based on Tobit Model to Empirical Analysis on the Factors Affecting the Photovoltaic Industry

摘要:

本文从微观角度出发以2007至2014年19家公司相对效率值为因变量,以偿债能力、运营能力、人均产值、研发能力、市场服务水平以及产业政策颁布种类数目等六个指标作为自变量,建立Tobit回归模型,考察中、美、日、韩四国产业发展变化及产业影响因素,结果显示资产周转率和销售费用率对企业效率影响最为显著,发现政策实施可对产业发展起到促进或者抑制的作用,提出规模与能力协调发展以及处理好政策与效率的关系。

Abstract:

From the microscopic point of view, this paper takes the relative efficiency of 19 companies from 2007 to 2014 as the dependent variable, and its solvency, operation capacity, per capita output, research and development capabilities, the service level of market and industrial policy promulgated species number , this six indicators as independent variables, using Tobit regression model to establish. Investigation with industry development change and industrial factors of China, the United States, Japan and South Korea. The results showed that asset turnover rate and cost of sales rate impacted on the efficiency of enterprises is the most significant and found that the implementation of the policy can promote or inhibit the effects on the industry development, put forward the coordinated development of scale and capacity and deal with the relationship between policy and efficiency.
