After the stationary test of the time sequence, I conduct the regression analysis of the relationship between freight volume and the total output value of agriculture, and the relationship between passenger capacity and the total output value of agriculture. In addition, I conduct Granger causality test of the relationship between freight volume and passenger capacity, and the total output value of agriculture. The results show that the transportation of Zhejiang Province has promoted the development of agricultural economy prominently, and the development of agricultural economy plays indistinctive role in promoting the transportation volume in Zhejiang Province.展开更多
