The Construction of Nonlinear Dynamic System Model of National Defense Expenditure and Economic Growth

摘要

At present, the domestic and foreign scholars mainly use the co integration test to study the relationship between defense spending and economic growth. These methods mainly study the relationship from the point of view of the data, which can only come to the long-term stable relationship or causal relationship between the two, not specifically found how the relationship between defense spending and economic growth is. In this paper, a dynamic economic approach is used to establish the DE-GDPNLDS nonlinear dynamic system model between defense expenditure and economic growth.
