Big data reference land price and land price automatic evaluation updating system

Abstract

The invention relates to a big data reference land price and land price automatic evaluation updating system, and relates to the technical field of land assessment. The big data reference land price and land price automatic evaluation updating system comprises a database management module, a land cadastral database, a reference land price module, a land market statistics module and an economic statistics module. The database management module is a database comprising fields of increasing valuation time points, market prices, price coefficients and the like; fields can be assigned in batches ata time; related departments of the local government store agricultural land, construction land and unused land parcels (including stock land and incremental land with planned land properties and landintensity indexes) which are all surveyed and mapped locally. According to the big data reference land price and land price automatic evaluation updating system, price assignment can be carried out on determined time points of each parcel in batches at the beginning, land price updating can be carried out by tracking changes of land market prices at any time, and the reference land price can be updated regularly.

Description

technical field [0001] The invention relates to a big data benchmark land price and an automatic evaluation and updating system of land price, and relates to the technical field of land evaluation. Background technique [0002] The country has relevant regulations that require governments above the county level to update the local benchmark land price in a timely manner, but the actual situation is that there is no condition to update it in a timely manner. It can only be about five years before entrusting an evaluation company to perform updated calculations and then provide updated results. It will be issued after acceptance by the provincial land management department. In the process of actual land management, when it is necessary to evaluate the price of each piece of land, it is also necessary to entrust an evaluation company to conduct manual evaluation at any time. After the evaluation company manually evaluates the land price, it provides a land price evaluation repo...

Problems solved by technology

[0006] The purpose of the present invention is to provide a big data benchmark land price and land price automatic assessment and update system to solve the problem that the existing land valuation theory and method proposed in the above background technology cannot update all land prices and benchmark land prices in real time, resulting in manual operation The artificial risk, the efficiency is low, and the price is unreliable. At the same time, the benchmark land price updated every few years is out of the market when it is released, and the guiding effect is weak.
