Study on optimum population of Qingdao City based on P-E-R model and cost-benefit model
Based on the P-E-R model,various indicators reflecting the level of economic development and resource utilization are selected.By using weighted analysis to establish a regression model,an investigation is carried out on the appropriate population size of Qingdao.At the same time,from the perspective of cost-benefit analysis,a model for measuring the appropriate population size is constructed to examine the quality of urbanization in Qingdao.This focuses on the development of new urbanization to provide resource allocation schemes and related suggestions for future population growth.The study found that Qingdao's economic population carrying capacity has a significant advantage and is much higher than the resource population carrying capacity.At this stage,Qingdao's population development conforms to the appropriate population size.There is some room for population growth,but the speed of population growth is lower than the national level.It is estimated that by 2035,the population of Qingdao will be about 12 million.
