Hi you may take a look three path mediation model from a paper by Wilderom et all 2015 to deal with this. I think you can remove "government participation" or you you can utilize this as moderator variable.(https://www.researchgate.net/profile/Celeste_Wilderom/publication/274142185_From_manager's_emotional_intelligence_to_objective_store_performance_Through_store_cohesiveness_and_sales-directed_employee_behavior/links/552524b40cf2b123c5178be5.pdf)

you should multiply each IV by each moderator variable in SPSS database. Then, in Amos, you should design you model considering the following observed variables: IVs, Moderator variables, and each IVxModerator variable.
Imagine that X is the IV, M is the moderator nd Y is the DV. You should design a model in AMOS taking X, M, and XxM as IVs and Y as DV.
Just one small addition to Lisete's answer: mean-centre the X and M variables before hand. The easiest way to do that is to z-score these variables in SPSS before then multiplying them together and saving this as s new variable. Mean-centering reduces the problem of coliniarity between the X IV and X*IV variables in the subsequent models. See Tabachnick and Fidell "using multivariate statistics" for more.
