| 中文摘要: |
| 主要研究我国生猪重大疫病风险评估的方法。通过将疫病风险与生猪死亡数之间的关系进行量化，并
利用蒙特卡洛模拟解决所需样本不足的问题；运用极值POT 模型对我国生猪疫病灾害损失尾部分布进行了有效拟
合，构建了生猪重大疫病损失的广义Pareto 分布模型。利用风险价值法，实证分析和度量了我国生猪疫病发生的风
险水平，计算出我国不同等级的生猪疫病风险损失的95%置信区间，构建了我国生猪疫病风险评估的基本框架，并
提出减轻和控制我国生猪重大疫病风险的政策建议。 |
| 英文摘要: |
| This paper studied an evaluation method for disease risk of pig industry in China. Making the relationship
between disease risk and the death of pigs, Monte Carlo simulation was used to expand sample size. Peak over threshold
approach based on the extreme value theory was used to fit the distribution of disease risk of pigs, and value at risk was
used to assess disease risk of pigs. The 95% confidence interval of the loss was calculated in the scenario of different level
of disease risk, a basic framework of the pig disease risk assessment was constructed. In the end, the advices of reducing
and controlling the disease risk has were put forwad. |
