Most　previous　articles　estimate　the　effects　of　information　communication　technologies　(ICTs)　on　economic　growth　average　using　national　data　without　consideration　of　heterogeneity　of　ICT　effects　on　cities　across　multiple　economic　development.　The　heterogeneity　of　ICT　effects　is　confirmed　to　promote　both　the　sustainability　and　equitableness　of　the　whole　cities.　In　order　to　investigate　the　heterogeneous　effects　of　ICT　between　developed　and　less　developed　cities,　a　quantile　spatial　autoregressive　(QSAR)　model　is　applied　to　estimate　coefficients　at　different　quantiles　while　accounting　for　the　spatial　dependence　of　urban　economy.　We　find　significantly　positive　effects　of　ICT　in　local　and　neighboring　cities　after　controlling　the　spatial　dependence　of　urban　economy.　We　have　further　found　larger　coefficients　of　ICT-related　variables　in　cities　with　lower　gross　domestic　product　(GDP)　per　capital　suggesting　that　digital　dividend　from　ICT　prefer　the　less　developed　cities　over　developed　cities.　Our　conclusions　indicate　there　would　be　＂double　dividend＂　from　ICT,　namely　an　improvement　of　both　overall　economic　growth　and　balanced　economic　development　among　cities.
