In the context of global integration, whether a diplomatic partnership strategy can promote outward foreign direct investment (OFDI) and how it works are very important issues for China. Based on a dataset featuring China's partnerships collected from the Ministry of Foreign Affairs website, we establish an empirical framework to assess the role of China's diplomatic strategy in its OFDI arising from...
When the Melitz model is implemented in practice, the industrial productivity distribution is often assumed to be of Pareto form. In this case, a fundamental relationship κ > σ − 1 must hold to guarantee the convergence of the industrial average productivity, where κ is the concentration degree of the industrial productivity Pareto distribution and σ is the substitution elasticity across varieties...
One-dimensional global optimization of a function f(x) in an interval D is still a difficult problem. In this paper, we pose a new method for finding the ε-global optimal value of f(x) in D. We first approximate the function f (x) via its partial sum of its Fourier series. We show that for given ε, we can find a partial sum sn(x) n of its Fourier series such that when n is larger than some...
In this article, we derive a new kind of uncertain optimization problem by incorporating fuzziness into robust optimization and thus obtain the so-called fuzzy robust optimization model. For the proposed fuzzy robust optimization model, we derive its deterministically equivalent form (which is just a traditional optimization problem) for the case that constraints are linear in the uncertainty parameters...
In this article, we derive a new kind of uncertain optimization problem by incorporating fuzziness into the current hot research topic robust optimization and thus obtain the so-called robust fuzzy optimization model. For the proposed robust fuzzy optimization model, we first derive its deterministically equivalent form(which is just a nonlinear optimization problem), and then analyze the property...
