This thesis adopts production value of population, GDP, industry, agriculture and the tertiary industry and data of expenditure in recent twenty years in every province, every district, every city, and figures out the coordinate of gravity center of each years. It quantitatively express developing evolvement of population, GDP, industry, agriculture, the tertiary industry and the consumption center of gravity. On the basis of the result, it analyses the developing evolvement and relation of China population and region discrepancy of economic developing. From the developing evolvement of gravity center we can draw a conclusion: the discrepancies between east and west in China existed twenty years ago, and the population gravity center slowly moves to southwest in China in recent twenty years; on the whole the movements of GDP, industry, the tert iary industry and the consumpt ion gravity centers show to southeast. Against the geometry center in China: on the whole the region discrepancy in China is extended; against the population gravity center: between east and west take on imbalance developing, while between south and north tend to balance; but the change of the agriculture gravity center shows irregularity. The thesis simply analyses driving gene of the developing evolvement of each factor.
