This　paper　establishes　a　two-stage　super-efficiency　data　envelopment　analysis　(DEA)　model　to　measure　the　technological　innovation　efficiencies　of　30　regions　and　34　sub-industries　in　the　manufacturing　industry　in　2005.　Based　on　the　two-stage　super-efficiency　model,　we　can　judge　whether　the　inefficiency　appear　in　the　first　stage,　the　second　stage　or　both.　Besides,　we　can　also　arrange　in　an　order　the　efficient　units.　Applying　the　data　of　the　manufacturing　industry　to　this　model,　this　paper　studies　empirical　research　on　the　innovation　efficiency　of　manufacturing　industry　and　draws　some　crucial　conclusions.
