查询词典 unique factorization theorem

The index system was first set up, which reflected the economy, society, resources and environment conditions in the district. Then, factorization method was employed by using the software SPSS to obtain comprehensive index numbers. The linear regression method and fuzzy mathematics method were used to compute the coordination degree of economy, society, resources and environment. Finally, on the basis of the status of comprehensive evaluation indexes and coordination degree of the district, the main problems in the sustainable development of Beibei District were found out and some suggestions were also proposed.
