With　the　progress　of　information　technology,　the　proportion　of　information　industry　income　in　China＇s　total　high-tech　industry　income　is　growing.　However,　there　are　obvious　regional　inequalities　in　the　development　of　China＇s　information　industry.　In　view　of　this　phenomenon,　this　paper　used　the　public　data　released　by　industry　and　the　National　Bureau　of　Statistics　of　China　to　study　the　factors　influencing　the　information　industry,　as　represented　by　the　development　of　the　telecommunication　industry　in　coastal　areas,　where　the　information　industry　is　more　developed.　Through　the　construction　of　a　multiple　regression　model,　the　main　factors　affecting　the　development　of　the　telecommunications　industry　in　coastal　areas　were　found,　and　other　secondary　factors　were　qualitatively　studied.
