摘要:Human resources development is one of the most important components of any organization and detecting important factors influencing human resources management plays an essential role in the success of the firms.In this study,we investigated different factors influencing human resources productivity of Shiraz University of Medical Sciences staff.Method: The present research was a cross-sectional study.Sample size was calculated 208 individuals.To access information about the human resource productivity,a valid and reliable questionnaire was used.The data were analyzed using SPSS software.Pearson correlation was used for statistical analysis of the data (p=0.05).Results:The results showed that there was a statistically significant relationship (p-value<0.001) between human resources productivity and factors affecting the productivity of human resources (motivational factors,leadership style,creativity and innovation,general and applied education,and competitive spirit).Motivational factors (r =0.89) and general education (r =0.65) had the most and the least effects on human resources productivity.Conclusion: Considering the fact that motivational factors were the most effective factors on human resource productivity,we recommend that managers should care more than before about this factor; also,in order to motivate the employees,they should consider the staff ’s individual differences.
