基于经费限额的备件订货方法研究

由于受国家经济体制和经济条件等因素的影响,器材备件的供应主要采取＂实物限额与经费限额相结合,以经费限额为主＂模式,要求器材管理部门,根据经费限额量,制定科学合理的器材订货计划,使有限的资源得到更充分的利用,以达到更好的军事经济效益。     

THE THEORY OF ENDOGENOUS MARKET STRUCTURES

Most market structures are neither perfectly or monopolistically competitive: they are characterized by a few large firms that are engaged in strategic interactions in their production and investment decisions and whose number is endogenous. The theory of endogenous market structures analyzes markets in partial and general equilibrium where strategies affect entry and entry affects strategies, and exogenous primitive conditions on technology and preferences affect the equilibrium. We discuss applications to industrial organization, international trade, business cycle theory, international finance, growth and implications for welfare and for competition, trade, fiscal and monetary policy.

考虑物料、产能和客户优先级三重约束的订单允诺管理问题研究

客户订单允诺管理是在市场全球化的背景下．综合考虑各种资源有限性,对客户的订单给予准确的答复．因而具有很好的应用前号。文章对现有客户订单允诺模型做出改进,在供应链资源即物料和产能双重限制下,加入客户优先级约束,通过建立模型求解,给出合理的客户订单允诺机制。文中不仅定性分析客户优先级．而且将客户优先级量化为客户价值来表示,使该订单允诺管理机制更为有效．更有利于企业的长期可持续发展。     

Market entry of firms with different legal forms: an empirical test of the influence of institutional factors

Drawing upon institutional theory we develop a conceptual model and investigate the determinants of market entry for worker cooperatives, publicly traded and limited-liability companies. Our results show that formal institutional conditions (i.e., mercantile legislation) influence the start-up choice of entrepreneurs regarding the legal form of their new venture. In addition, we take into account the influence of informal institutional conditions (i.e., local corporate culture) on the market entry rate of firms with different legal structures. Findings show that, while market entry is sensitive to the general economic climate, entry rates of firms with a different legal structure respond differently to the same economic conditions.

Variation diminishing property of densities of uniform generalized order statistics

Let f _*,r , r ≥ 1, denote the density function of rth uniform generalized order statistics as defined by Kamps (1995) or Cramer and Kamps (2003). We prove the following variation diminishing property: the number of zeros in (0,1) of any linear combination does not exceed the number of sign changes in the sequence (a ₁, . . . ,a _r ). This result is applied to study monotonicity and convexity properties of f _*,r .
