主要内容：

We consider a contest model in which players can simultaneously participate in multiple battles with heterogeneous valuations and sizes. The conflict structure, indicating which players participate in which battles, can be represented by a hypergraph. We focus on semisymmetric hypergraphs, and fully characterize the equilibrium effort profiles and payoffs under both two scenarios: uniform effort (UE) in which each contestant is restricted to exert the same effort across all the battles she participates, and discriminatory effort (DE) in which such a restriction is lifted. When the contest success function in each battle is of Tullock form, a surprising neutrality result holds: the aggregate actions under two regimes are the same. We also show that, in some sense, the Tullock form is also necessary for the neutrality result.
