The　literature　about　changes　in　land　use　includes　many　studies　of　global　sustainable　development　goals,　while　studies　of　transport　land　expansion　have　been　relatively　scarce.　In　this　paper,　we　present　an　analysis　of　the　spatiotemporal　characteristics　of　transport　land　expansion　in　China＇s　31　provinces　from　2009　to　2017,　applying　the　spatial　Dubin　model　to　identify　the　factors　that　influenced　changes　in　per　capita　transport　land　area　(PCTLA).　The　eastern　and　western　regions　have　continued　to　lead　the　nation　in　terms　of　the　total　area　dedicated　to　transport　land.　The　expansion　speed　of　transport　land　in　the　central　and　western　regions,　however,　has　been　faster　than　in　the　eastern　and　northeast　regions.　As　for　PCTLA,　the　western　region　had　the　greatest　amount　and　the　central　region　the　least.　Further,　PCTLA　showed　significant　spatial　autocorrelation.　Economic　development,　government　regulations,　industrial　structure,　and　the　extent　of　opening　up　and　urbanization　had　significant　positive　impacts　on　PCTLA,　while　the　development　of　railway　freight　had　a　negative　impact.　This　paper　concludes　with　some　policy　suggestions　for　optimizing　transport　investment,　accelerating　the　adjustment　of　industrial　structure　and　transport　structure,　and　implementing　high-quality　urbanization.　The　results　should　be　of　interest　to　those　involved　in　the　sustainable　development　of　transport　systems.
