Research And Realization Of Analyzing And Forecasting System For Macro-economics Indexes

With rapid development of productivity in modern society, quantity of economy information increases dramatically, the structure of economy information is also becoming more and more complex. Now, many countries adopt governmental influence and national plan on economy developing, so, it is necessary to develop research on Macro-economics analyzing .With the development of modern economy theories and national economy calculation system, extensive application of mathematics methods and the booming of computer technologies and modern communication technologies, people can build Macro-economics analyzing and forecasting system to gather economy information and study economy indexes, provide accurate and valuable conclusions for decision-making organization.The Analyzing and Forecasting System for Macro-economics Indexes mentioned in this paper, is build in demand of quantificationally studying the Macro-economics indexes and their relations. The system introduced computer techniques, database theories and economy forecasting methods, a complete national economy indexes database is built in the system, the system integrate a set of analyzing and forecasting methods for studying of macro-economics indexes. User can view the statistic and chart for the indexes, get character and forecast value and make valuable conclusion with the system. The system can effectively analyze and supervise the status of Wuhan economy, provide valuable information for decision-making and status warning for users.This paper mainly discussed the basic functions, architecture and realization of the system, described as follows:I. Build database for all the economy indexes in Wuhan of the past more than 50 years after liberation, including 18 databases and 307 tables.II. Build Multi-variable Statistic Analyzing Model, provide methods for reducing irrespective indexes, etc.III. Build Index Forecasting Model, provide methods for forecasting the economy indexes in future and supervising the economy status.IV. Propose method for building each component for the system.
