We also tested the model and proposed propositions by a sample evaluation method, specifically with 1 000 copies of questionnaires given out to managers or directors of MNEs’ subsidiaries in China Mainland and resulting in 151 sets of valid answers. The empirical study supports that national differences between the parent country and the host country and the strategies employed by MNEs do have impact on the subsidiary staffing, and MNE headquarters should make different staffing plans according to the difference of nations and strategies. We welcome testing our model by peer researchers in other country.展开更多

The method, which is evolved from the first order derivative test for optimality of the Lagrangian function with respect to the primary variables of the problem, decomposes the solution process into two independent ones, in which the primary variables are solved for independently, and then the secondary variables, which are the Lagrange multipliers, are solved for, afterward. This is an innovation that leads to solving independently two simpler systems of equations involving the primary variables only, on one hand, and the secondary ones on the other. Solutions obtained for small sized problems (as preliminary test of the method) demonstrate that the new method is generally effective in producing the required solutions.展开更多
