With　the　knowledge　economy　era,　knowledge　workers　have　been　regarded　as　the　intangible　asset　in　an　organization　and　played　a　leading　role　to　support　an　organization＇s　innovative　competence;　therefore,　knowledge　workers＇　capabilities　of　knowledge　exploration　and　knowledge　exploitation　are　expected　to　improve　an　organization＇s　competitiveness.　This　study　aims　at　analyzing　the　effect　of　knowledge　exploration　and　knowledge　exploitation　on　procedural　justice.　The　population　of　the　research　consists　of　IT　engineers　in　Taiwan　with　the　sample　size　of　104　subjects　who　were　selected　based　on　convenience　sampling.　Data　analysis　was　done　using　IBM　SPSS　22.　The　results　show　that　knowledge　exploration　is　positively　correlated　to　knowledge　exploitation　and　organizational　justice,　and　knowledge　exploitation　is　positively　correlated　to　organizational　justice.　©　2018　Association　for　Computing　Machinery.
