A　favorable　industrial　environment　is　important　for　increasing　the　sophistication　and　competitiveness　of　a　country＇s　exports.　However,　a　country＇s　industrial　environment　is　bound　to　change　dynamically.　Therefore,　this　study　explores　the　impact　of　industrial　environment　uncertainty　on　export　complexity.　Through　an　empirical　analysis　of　panel　data　from　76　countries　from　2010　to　2020,　we　find　that　political　and　social　uncertainty　significantly　inhibits　exports,　while　an　uncertain　economic　environment　significantly　complicates　exports.　Moreover,　uncertainty　in　the　industrial　environment　affects　high-　and　middle-income　countries　more　than　low-income　countries.　Furthermore,　the　analysis　of　regulatory　effects　shows　that　political　uncertainty　and　social　uncertainty　have　a　substitution　relationship　in　inhibiting　export　complexity.　This　study　affirms　the　impact　of　industrial　environment　uncertainty　on　a　country＇s　export　capabilities　and　provides　a　reference　for　countries　with　different　incomes　to　formulate　and　modify　their　industrial　environment　policies.
