The barycenter calculated by composite proportion is parameterized according to the data of statistical yearbooks to calculate and interpret the geometry barycenter of land and entirely territory,as well as the barycenter of population,economy,ecology,water resource,and commissariat.By comparing the distance between the barycenters and Beijing,we find that the deviation is about 620 to 1487 km,which is not good for region administration.Besides,we analyze Beijing's problem within the confines of the factors such as water,gas,landform,geology and earthquake after establishing capital in Beijing 61 years later.We discuss the area of the fullest water, the martial security area under threat of nuclear warfare,the area of the most products,and the area of the best anthropogeography in the best location for establishing a new capital.Finally,we evaluate the loss and benefit,physical cost and opportunity cost,development of Beijing after its moving to a new place,and choice of moving or not using different evaluation methods.
