Firstly, we construct the test of the exogenous structural mutation for a unit root process and this eliminates the influences on the model from the mutation of the data growth process.

Unit-root test, Co integration test and Granger Causality test are applied to analyze factors of construction industrial growth.

This paper uses unit root test model, co-integration test model and Granger Causal test model, to analyze the relation between international tourism and economic growth of Guilin.
