Macroeconomic analysis method and system based on internet big data

Abstract

The invention discloses a macroeconomic analysis method based on internet big data. The method comprises the following steps: crawling target macroeconomic parameters on each network base station by adopting a web crawler module; preprocessing target macroeconomic parameters through an attribute reduction algorithm based on inter-class discrimination; operating a preset macroeconomic parameter classifier and / or a macroeconomic parameter classification algorithm based on Hadoop to realize classification of macroeconomic parameters to obtain a target macroeconomic parameter set; according to theclassification result of the macroeconomic parameters, operating a preset feature parameter extraction model and / or a feature parameter extraction algorithm based on Hadoop to achieve extraction of feature parameters of the target macroeconomic parameter set; and operating a preset macroeconomic analysis model and / or a macroeconomic analysis algorithm based on Hadoop to realize evaluation of thetarget macroeconomic parameter set according to the feature parameters, and outputting a corresponding evaluation result. According to the invention, more accurate and credible analysis can be carriedout on complex macro-economy.

Description

technical field [0001] The invention relates to the field of big data analysis, in particular to a macroeconomic analysis method and system based on Internet big data. Background technique [0002] In the Internet age, big data has been applied to many areas of social economy and life. With the rapid development of e-commerce, Internet finance, social networks, etc., the amount of data generated by people's various behaviors of shopping, communicating, searching, and browsing on the Internet is increasing. In the context of the era of big data, macroeconomic analysis with the help of big data has become one of the important tools and means to promote economic and social development. [0003] At present, the traditional macroeconomic analysis generally has the following defects: [0004] (1) The traditional economic analysis method is mainly based on sampling statistics, and the analysis is carried out by considering the sample as a whole. However, there will be certain err...

AI Technical Summary

Problems solved by technology

[0004] (1) The traditional economic analysis method is mainly based on sampling statistics, and the analysis is carried out by considering the sample as a whole. However, such a hypothetical analysis will have certain errors

[0005] (2) The traditional economic analysis method is centered on analyzing the causal relationship of things. However, because the causal relationship of economic variables is often difficult to test or is affected by many other variables, economic analysis often consumes a lot of time and energy, and The conclusion is not necessarily accurate

[0006] (3) Traditional economic analysis methods rely too much on statistical data released by various departments, so they cannot obtain macroeconomic development data in a timely manner, and there is a lag in macroeconomic analysis, which is unfavorable for the prediction of the macroeconomic situation
