Research on the Interactions between the Tertiary Industry and the Primary/Secondary Industries in Henan Province

With a mathematical model on the relationship between the primary industry and the tertiary industry and a mathematical model on the relationship between the secondary industry and the tertiary industry in Henan Province,their interactions are studied in the assumed short-tem equilibrium and long-term equilibrium.Using the impulse response function and variance decomposition model,the dynamic interactions are also discussed.Finally,on the basis of the quantitive analysis result,the conclusion that the industry structure of Henan Province is unreasonable is drown and the policy proposal that Henan province should strengthen the development of the tertiary industry is made to promote the development of the primary and secondary industries.
