Abstract

Macroeconomic forecasting is guided by rational expectation, which emphasizes various historical information used. It is similar to using historical data to predict macroeconomic development trends. When making investment decisions, enterprises generally need to consider the cost of investment. The economic downturn seems to have entered a bottomless pit. The main reason is that although the government has stabilized the economic growth through large-scale stimulus policies, it also hinders the process of economic natural adjustment, leading to the artificially prolonged market economic cycle. Therefore, in order to effectively deal with this complex situation, we must rely on a more mature theory and method system to systematically analyze the transmission mechanism that affects enterprise investment decisions. This paper will analyze the macro-economy based on big data. The development strategy of big data has become a hot issue for enterprises around the world. Many enterprises integrate big data strategy with their own decisionmaking management system, and make more scientific decisions through comprehensive collection, screening and analysis of all kinds of data.
