The Grey Simulation of Gross Value of Construction Industry in Central China

摘要

as a major industry in China, construction industry value weights a lot in GDP. In order to better simulate the development trends of this industry in Central China, this paper propose the first-order one-variable grey differential equation model (abbreviated as GM(1,1) model) from grey system theory as the main simulation tool. The conclusion is that the growth trends of Anhui, Jiangxi, Hubei and Hunan can be directly simulated. Through using smoothing processes and sensitivity analysis methods, the gross values of Shanxi and Henan can also be depicted with differential equations.
