Regional economic vitality is an important composition of the city's comprehensive competitiveness. The core goal of this article is to establish a scientific mathematical model based on the relevant data, to grasp the key factors that effectively improve the regional economic vitality and to provide advice for the benign economic vitality of Shenzhen’s region sustainable development and stronger regional competitiveness. Firstly, Shenzhen was selected as the reference area. The factors affecting economic vitality were analyzed from the three aspects—population, number of enterprises, and output value of enterprises. Based on the quantified results, it was concluded that the regional economic vitality was improved. Secondly, based on the previous conclusions, we use the gray prediction model to accurately describe the predicted values of each independent variable after the economic policy transition and compare them with the real values. After analyzing the comparison between the predicted value and the true value, the conclusion is that the economic policy transition has a short-term impact on the economic vitality of the region. The impact is more significant and the long-term impact is smaller. Thirdly, we use gray correlation analysis to analyze and measure the regional economic vitality as well as quantitatively sort the urban economic vitality. With the help of computer programming technology, we can minimize the loss due to information asymmetry. The comparison of reference regions gives the ranking of urban economic vitality: Shanghai first, Shenzhen second, and Beijing third.
