The sureness of the common influence factor to the price of land among the cities passes gradual Return Law in mathematical statistics, screen the influence factor of the urban price of land progressively, set up the return equation of the influence factor of the price of land, predict the future tendency of the price of land.
Second,bigger degree gives play to the market to dispose the function of the land resource,should continue perfecting and employing and striking the system of hanging, workout and implement the operational right to use the land of urban area of Hengshui andsell the plan, promote the land to utilize intensivly, strengthen government'scentralized power and unity management to the land, strengthen and perfect themanagement of the urban price of land.
In addition to the identification of submarkets, intra-urban price indices will also be estimated.
However, as greater quantities of data within a single metropolitan become obtainable, the idea of building intra-urban price indices is achievable.
The significance of urban land price index is discussed in this paper. To the actual situation in our country, the hide price for contract price in private houses busimeses is revised by mathematical model. According to annual average value revised, the approximate determination method of urban price is first put forward. Examplified by the practice in Quzhou City. the comparison and the error analysis are also given out to demonstrate the practice of the method.
