英文摘要：

This paper gives an overview of advances of shock models during the latest 3 decades. We also present an introduction to δ- shock model proposed by us with newly established results. Based on the cluster marked point process, a general framework is investigated. Finally, as a particular case of the framework, we introduce and analyze a new insurance risk model.
