Based　on　view　of　information　spillover,　we　measure　degree　and　direction　of　risk　spillover　in　China　from　dynamic　and　static　perspectives,　identify　risk　centers　and　their　evolution　within　crisis　applying　methods　of　spillover　index　and　complex　network.　The　results　show　that　the　risk　spillover　effect　in　China　is　fluctuant,　uncertain　and　asymmetric,　and　strong　connectedness　and　obvious　hysteresis　effect　exist　in　financial　markets;　the　degree　of　receiving　risks　is　opposite　to　that　of　transmitting　risks　when　markets　impacted　by　extreme　events;　the　currency　market,　especially　the　inter-bank　repo　market　is　the　risk　center　of　financial　system　with　the　strongest　risk　spillover　effect　but　weaken　during　financial　crisis.　However,　risk　spillover　effect　of　metal　market,　stock　market　and　real　estate　market　enhance　significantly　during　financial　crisis;　bond　market　and　foreign　exchange　market　receive　the　most　risks.　©　2017,　Editorial　Board　of　Journal　of　Systems　Engineering　Society　of　China.　All　right　reserved.
