通过引入邮电资源紧缺度概念来定量描述我国不同地区在不同时期的邮电资源紧缺程度，并根据投入产出法确定的１９８７年全国部分省市邮电通信产品的影子价格，分析研究了我国不同地区邮电资源紧缺度与邮电通信产品影子价格的相互关系。结果表明，我国不同地区的邮电资源紧缺度与邮电通信产品影子价格之间存在较好的统计线性关系，文中给出了描述这种关系的多元线性回归方程。
By introducing the concept of the shortage of post and telecommunications resources to quantitatively describe the different regions in our country in different periods of posts and telecommunications resources shortage, and according to the input-output method to determine the shadow prices of some provinces and cities in 1987, postal communications products in China analyzed the different regions of China post and telecommunications The relationship between resource shortage and the shadow price of post and telecommunications products. The results show that there is a good statistical linear relationship between the shortage of post and telecommunications resources and the shadow price of post and telecommunications products in different regions of China. In the paper, a multivariate linear regression equation describing the relationship is given.
