Research on the Relationship between China’s fixed asset investment in the whole society and its influence factors

摘要

Vector Autoregression Model (VAR) is applied to study the relationship between China's fixed asset investment in the whole society and its influence factors in this paper. The main influencing factors of fixed asset investment studied in this paper are the ratio of money supply to GDP, total import and export and total population. The conclusion is that the ratio of money supply to GDP and the total population at the end of the year have significant negative impacts on fixed asset investment in the whole society. The fixed asset investment in the last period has a significant positive effect on the fixed asset investment in the current period, which indicates that the investment of fixed assets in the whole society has certain inertia and stickiness. In terms of granger causality, the ratio of money supply to GDP, the total population at the end of the year and total import and export are granger reasons for the fixed asset investment in the whole society.
