Numerous　studies　have　suggested　that　the　perceived　built　environment　is　shaped　by　the　objective　built　environment　and　influences　human　physical　activity.　However,　the　empirical　examination　of　this　pathway　remains　scant.　Addressing　this　gap,　our　study　investigates　whether　the　built　environment　affects　leisure-time　physical　activity　through　its　impact　on　the　perceived　built　environment,　utilizing　data　collected　from　760　residents　in　Fuzhou,　China.　Structural　Equation　Modeling　results　reveal　a　modest　correlation　between　objective　and　perceived　built　environment　elements,　with　the　objective　built　environment　being　a　stronger　predictor　of　leisure-time　physical　activity.　Notably,　perceived　recreational　facilities　significantly　mediate　the　relationship　between　objective　recreational　facilities　and　leisure-time　physical　activity,　accounting　for　15%　of　the　variance　in　physical　activity　due　to　objective　recreational　facilities.　This　mediation　effect　is　consistent　across　subpopulations,　irrespective　of　residential　self-selection　biases.　These　results　highlight　the　imperative　for　urban　planning　and　policy　to　extend　beyond　mere　spatial　allocation　of　amenities　to　enhancing　both　the　actual　and　perceived　accessibility　of　these　facilities,　thus　underlining　the　study＇s　profound　implications　for　public　health　and　urban　development　strategies.
