With　the　rapid　increase　of　high　speed　rail　(HSR)　network　and　air　travel　network　in　China,　the　intercity　accessibility　is　reshaped.　This　study　aims　to　measure　the　intercity　accessibility　by　considering　the　two　modes.　Based　on　the　current　networks,　timetable　and　socioeconomic　data,　this　study　utilizes　connectivity,　cumulative　opportunity　accessibility　and　potential　accessibility　to　calculate　intercity　accessibility　in　the　network　consisting　of　36　major　cities　in　China.　Furthermore,　the　relative　and　weighted　average　intercity　accessibility　of　the　two　modes　are　obtained　to　provide　a　comparison　and　overall　evaluation.　The　results　indicated　that　the　selected　indicators　are　effective　to　evaluate　the　accessibility　from　different　perspectives.　The　intercity　accessibility　shows　different　spatial　distributions　in　HSR　and　air　travel.　Besides,　the　air　travel　network　has　higher　equity　than　the　HSR　network　in　all　accessibility　measures.　Furthermore,　it　is　found　that　the　correlation　between　the　potential　accessibility　and　economic　development　is　stronger　than　that　of　others.　This　study　can　provide　some　advices　for　the　further　development　of　the　HSR　and　air　travel.　©　2023
