This paper attempts to analyze the relationship between drought disaster area and direct economic loss in Yunnan Province based on the method of co-integration test and the error correction model. Firstly, the stationarity of the sequence is judged according to the auto-correlation and partial auto-correlation analysis diagrams of the sequence and the results of ADF test; Then, the OLS regression model of first-order difference sequence is established. Combined with the residual sequence of OLS estimation and the results of ADF test, it is concluded that the sequence has a co-integration relationship; Finally, the ECM model with error correction term is established. It is found that the model has a good fitting effect, and can well describe the short-term fluctuation and long-term equilibrium relationship between drought disaster affected area and direct monetary loss series.
