The　development　of　the　Internet　has　provided　firms　with　the　ideal　opportunity　to　make　up　for　the　knowledge　gap　for　achieving　internal　knowledge　generation　(IKG)　and　external　knowledge　acquisition　(EKA).　It　is　worth　exploring　how　Internet　resources　can　be　used　to　satisfy　organizational　knowledge　needs　efficiently　to　adapt　to　dynamic　environments.　Thus,　according　to　the　resource-based　view,　knowledge-based　view,　and　contingency　theory,　we　study　the　impact　of　different　types　of　Internet　resources　on　the　two　modes　of　knowledge　creation　(IKG　and　EKA),　as　well　as　the　moderating　effect　of　environmental　dynamism　(ED)　on　this　relationship.　The　hypothesized　relationships　were　tested　using　the　hierarchical　regression　analysis　method　with　survey　data　collected　from　399　Chinese　firms.　We　found　that　Internet　relationship　resource　and　Internet　human　resource　can　simultaneously　facilitate　IKG　and　EKA,　while　Internet　infrastructure　resource　positively　affects　IKG　but　has　no　significant　impact　on　EKA.　Furthermore,　ED　positively　moderates　the　relationship　between　Internet　relationship　resource　and　IKG　and　EKA,　but　negatively　moderates　the　relationship　between　Internet　human　resource　and　EKA.　©　2018,　Operations　Research　Society　of　China,　Periodicals　Agency　of　Shanghai　University,　Science　Press,　and　Springer-Verlag　GmbH　Germany,　part　of　Springer　Nature.
