Analysis of the Relationship between China´s Log Imports and Disaster of Forest Pests

We analyzed the relationship between China´s Log imports and Disaster of Forest Pests empirically by cointegration theory and Granger causality test. The research shows that there is long-term and stable balance relationship between China´s Log imports and Disaster of Forest Pests, in which one-way Granger causality exists and it can rebanlance by 35% if unbanlanced in short term. Accordingly, this paper concludes that it is impossible for China´s Log imports policies. we try to put forward proposals to achieve sustainable development of China´s forest industry by controlling Disaster of Forest Pests.
