Emerging　technologies　have　a　variety　of　characteristics,　this　resulting　large　number　of　technology　analysis　methods.　With　continuous　construction　of　the　network　infrastructure　and　expanding　of　user　groups,　the　network　data　is　increasingly　important.　Consider　the　fact　that　various　subjects　in　real　life　will　show　their　own　behavior　in　the　network,　analyzing　the　link　between　sites　can　be　helpful　for　researchers　to　find　the　relationship　among　various　subjects,　thus　accurately　determine　the　stage　of　technological　development　and　guide　the　direction　of　technological　development.　By　studying　network　link　as　the　data　source　and　analyzing　cloud　computing,　conclusions　can　be　drawn　that　cloud　computing　technology　is　at　the　stage　of　transformation　from　research　and　development　(R&D)　to　industrialization,　the　technology　is　in　rapid　development　phase　and　so　on.　The　feasibility　of　network　data　used　for　technical　analysis　is　also　proved.
