| Abstract: | The series of China's urban and rural resident's average vegetable consumption was transformed into different state or the probability of transferring state.Using the principal of Markov Chain,the mathematical expectation of the increasing rate over the long term change was obtained.The trend of vegetable consumption per capita of China's urban and rural residents was analyzed. |

| Keywords: | Markov chain limit of probability mathematical expectation vegetable consumption |
