We perform a next-to-leading order QCD analysis to world data on polarized structure functions g1 and g2 in fixed-flavor number scheme. We include target mass corrections and higher twist effects in our fitting procedure and study their non-negligible effects on physically interesting quantities. Twist-3 contributions to both polarized structure functions are determined and the accuracy of the extracted polarized parton distribution functions (PPDFs) is improved. 3He and 3H polarized structure functions are described based on our fit result. Moreover, sum rules are derived and compared with available theoretical and experimental results
