Aimed　at　the　scarcity　of　mechanics　in　discrete　manufacturing,　this　paper　analyses　the　production　mode　of　discrete　manufacturing　and　its　special　characteristics　of　labor　demand　firstly.　Based　on　the　extensive　management　and　special　vocational　cycle　which　brings　team-building　drawbacks　and　resignational-emotion　fluctuations,　causes　for　scarcity　of　this　group　is　discussed.　Then　from　the　new　generation　mechanic　group　supplies,　knowledge　management,　position　supporting,　employee　orientation　and　humanized　management,　countermeasures　for　solving　this　problem　is　put　forward.
