Prenatal　health　care　interventions　are　effective　ways　to　improve　maternal　and　neonatal　health.　There　have　been　few　large　investigations　conducted　on　the　inequalities　in　maternal　health　services　utilization　in　Shaanxi　Province　of　west　China　since　the　health　care　reform　in　2009.　This　study　examined　the　inequalities　and　determinants　of　maternal　health　services　utilization　in　Shaanxi　Province.　A　household　survey　was　conducted　from　August　to　November　in　2013.　By　using　a　multistage　sampling　method,　local　women　aged　15-49　who　had　given　birth　in　the　preceding　three　years　were　recruited.　Information　including　social-demographic　characteristics　and　maternal　health　services　utilization　was　collected　through　a　face-to-face　interview.　A　concentration　index　approach　was　used　to　measure　inequalities　in　maternal　health　services　utilization.　A　logistic　regression　model　was　employed　to　investigate　the　determinants　of　maternal　health　services　utilization.　There　were　8,488　women　from　urban　areas　and　18,724　women　from　rural　areas　enrolled　in　this　study.　The　concentration　index　for　all　the　indicators　of　maternal　health　services　utilization　showed　significance　in　these　two　areas.　In　urban　areas,　the　concentration　index　of　having　5　or　more　prenatal　visits,　receiving　the　first　prenatal　visit　within　12　weeks,　delivering　at　secondary-or　higher-level　health　facilities　and　delivering　by　C-section　were　0.0356,　0.0166,　0.0177　and　0.0591,　respectively,　while　in　rural　areas,　the　corresponding　figures　were　0.0385,　0.0183,　0.0334　and　0.0566,　respectively.　The　determinants　related　to　maternal　health　services　utilization　were　women＇s　age　at　delivery,　educational　level,　employment　status,　parity,　health　problems　during　pregnancy　and　household　income.　Inequalities　in　maternal　health　services　utilization　still　exist　in　Shaanxi　Province.　Providing　maternal　health　services　for　younger,　less　educated,　unemployed,　high　parity　and　poorer　women,　especially　in　rural　areas,　is　expected　to　reduce　the　inequalities　in　maternal　health　services　utilization.
