This paper discusses the measurement of non-life insurance output and added value in the background of catastrophes, using the data of Guangdong province in China. The SVM method is applied to estimate expected claim rates in the paper. We found that the data of claim rate two years before has a primary impact on the present year's expectation in Guangdong. And the output of Guangdong in 2006 and 2007 might be underestimated, and the added value of Guangdong insurance industry might be overrated a little more. After that, future work is put forward.
