Based　on　the　analysis　of　highway　transportation　development　target,　the　social-economic　development　target　and　their　correlation　an　evaluating　indicator　system　is　set　up　which　coordinates　the　area　highway　transportation　with　the　social　economy　development.　By　taking　China＇s　mainland　31　provinces　(municipalities,　autonomous　regions,　target　statistical　data　in　2004　as　an　example　standardized　processing　and　the　principal　components　analysis　of　the　sampled　data　were　conducted　by　using　the　SPSS　statistics　software.　Three　principal　components　were　oblained.　The　synthesis　score　of　various　regions　by　various　principal　components　score　with　principal　components　weight　was　achieved　by　synthesis　computation.　Finally,　the　degree　of　coordinating　development　of　various　regions　is　classified　by　the　synthesis　score,　and　the　analysis　appraisal　is　carried　out　in　order　to　provide　reference　for　explaining　the　coordinated　development　between　highway　transportation　and　social　economy.
