Profit model is the strategic issue in the media industry. The dual sales is the core of the media industry.There are some defaults in the profit models such as single, linear and low value-added in the converging trend in the media industry.As the impact of convergence in the media industry appear gradually, the value chain of media industry take on network-based, flexible and similar structure.The innovation of profit model in media industry should focus on value-added, value chain transformation and governance of the value chain management.

内容提要：盈利模式问题是媒介产业发展中的一个战略性问题，二次销售模式作为媒介产业的核心模式在媒介融合的进程中逐渐显露出其单一化、线性化和低增值化的缺陷，由于媒介融合的影响，媒介产业价值链出现网络化、柔性化和同构化的发展趋势，媒介产业在此趋势中应通过价值增值、价值链转换和加强价值链治理实现盈利模式的创新。

PSO is a population-based optimization algorithm, which mimics the social behavior of animals in a flock. It makes use of individual and group memory to update each particle position allowing global and local search optimization. The objective function considered was the total weight of the structure subjected to stresses, displacements and forces constraints. The effects of the parameters were investigated as well and such combination of tuning parameters promote a better global search behavior avoiding premature convergence while rapidly converging to the optimal solution. Results showed the effectiveness of the proposed method by comparing with ANSYS Design Optimization Tool (zero-order method). The PSO with the tuning parameters makes it an ideal method for offshore wind turbines foundations optimization tasks.(2) A reliability analysis method for pile foundation bearing axial loads based PSOThe performance function of pile foundation's axially bearing capacity sometimes is nonlinear and complex, on the basis of geometric meaning of structural reliability index, an optimum model with PSO for structural reliability analysis under arbitrary random variables was established, The PSO algorithm is very efficient to solve global optimization problemsIts use in structural reliability field presents not only the advantage of its facility of implementation, but also the possibility to obtain the design point and the failure probability with a good accuracy. In addition, PSO is a zero order algorithm, for no derivative is necessary for its implementation.
