A　network　is　composed　of　many　network　nodes,　so　the　analysis　and　evaluation　of　the　target　node　is　of　great　importance,　especially　in　complex　networks.　For　this　purpose,　this　paper　established　an　analysis　model　of　target　nodes　for　a　complex　network　to　study　the　correlation　between　the　two　and　explore　the　searching　mechanism　of　target　nodes　in　the　complex　network.　Besides,　the　importance　and　reliability　of　the　target　nodes　were　simulated.　The　results　showed　that　the　analysis　of　the　target　nodes　had　a　great　effect　on　the　research　of　the　target　nodes　and　played　a　positive　role　in　the　research　of　the　whole　complex　network.　©　2018,　©　2018　Taru　Publications.
