为了研究辽宁物流投资对辽宁工业发展的贡献,利用柯布—道格拉斯生产函数构建辽宁工业总产出模型,并利用曲线回归的方法,通过考核曲线斜率的变化,研究不同时期辽宁物流投资对辽宁工业发展的贡献。通过研究得出,目前辽宁物流投资对辽宁工业发展的贡献率是正值,并且这个贡献率在逐年增长。
In order to study the contribution of Liaoning’s logistics investment to the industrial development of Liaoning, the Cobb-Douglas production function was used to construct Liaoning’s total industrial output model. Using the method of curve regression, the changes in the slope of the assessment curve were used to study Liaoning’s logistics investment in different periods for Liaoning’s industry. Contribution to development. Through research, it is concluded that the contribution rate of Liaoning logistics investment to industrial development in Liaoning is positive, and this contribution rate has been increasing year by year.
