We propose a solvable aggregation model to mimic the evolution of population A, asset B, and the quantifiable resource C in a society. In this system, the population and asset aggregates themselves grow through self-exchanges with the rate kernels K-1(k, j) = K(1)kj and K-2(k, j) = K(2)kj, respectively. The actions of the population and asset aggregations on the aggregation evolution of resource aggregates are described by the population-catalyzed monomer death of resource aggregates and asset-catalyzed monomer birth of resource aggregates with the rate kernels J(1)(k, j) = J(1)k and J(2)(k, j) = J(2)k, respectively. Meanwhile, the asset and resource aggregates conjunctly catalyze the monomer birth of population aggregates with the rate kernel I-1(k, i, j) = I(1)ki(mu) j(eta), and population and resource aggregates conjunctly catalyze the monomer birth of asset aggregates with the rate kernel I-2(k, i, j) = 12ki(nu) j(eta). The kinetic behaviors of species A, B, and C are investigated by means of the mean-field rate equation approach. The effects of the population-catalyzed death and asset-catalyzed birth on the evolution of resource aggregates based on the self-exchanges of population and asset appear in effective forms. The coefficients of the effective population-catalyzed death and the asset-catalyzed birth are expressed as J(1e) = J(1)/K-1 and J(2e) = J(2)/K-2, respectively. The aggregate size distribution of C species is found to be crucially dominated by the competition between the effective death and the effective birth. It satisfies the conventional scaling form, generalized scaling form, and modified scaling form in the cases of J(1e) < J(2e), J(1e) = J(2e), and J(1e) > J(2e), respectively. Meanwhile, we also find the aggregate size distributions of populations and assets both fall into two distinct categories for different parameters mu, nu, and eta: (i) When mu = nu = eta = 0 and mu = nu = 0, eta = 1, the population and asset aggregates obey the generalized scaling forms; and (ii) When mu = nu = 1, eta = 0, and mu = nu = eta = 1, the population and asset aggregates experience gelation transitions at finite times and the scaling forms break clown.
