基于经济绩效的国防工业市场最优集中度研究

以满足企业利润最大化和社会福利最大化双重效率标准的思想为基础,通过拟合我国国防支出需求函数和国防工业企业的成本函数,对我国国防工业市场最优集中度进行了理论研究,得出最优企业数量的一般表达式,并以我国航空工业上市公司为例,对其市场集中度展开了系统性估算。研究结果表明,我国国防工业产业的最优企业数量可以根据相关数据与拟合出的参数得到一个明确的数值,并且我国国防工业产业的最优市场集中度表现为适度集中,而在特殊情况下表现为完全集中。我国航空工业上市公司的最优企业数量为14家时,能够满足企业利润最大化与市场出清的双重标准,市场集中度达到最优。     

Competing for Control over the State: The Case of Yemen

Abstract

This article argues that the current conflict in Yemen is better understood as a competition over who controls the state, rather than as a conflict between the state and a non-state actor. It traces the development of the Houthis and shows how the movement managed to seize key government institutions. However, the Houthis lack internal legitimacy and have not been able to position themselves as a nationally relevant political elite. The fragmentation of the Yemeni state has resulted in a shift to more localized struggles over access to resources and power that involve both internal and external actors.     

From Westphalian Failure to Heterarchic Governance in MENA: The Case of Syria

Abstract

The problematic export of the Westphalian system to MENA is examined, taking Syria as exemplar. The export model is juxtaposed to actual non-lineal trajectories, semi-sovereignty and hybrid or failing states. This is manifested in post-uprising Syria in failing statehood, fragmented and overlapping governance, permeable and collapsing borders, the loss of sovereignty to trans-state movements, “competitive regime-building” between the Asad regime and jihadist warlords, and “competitive interventionism” by external powers filling the governance vacuum with their own proxies. The result is heterarchic zones of limited statehood in which state sovereignty is contested by both international (supra-state) penetration and sub-state fragmentation.     

Israel’s Security Nexus as Strategic Restraint: The Case of Iran 2009–2013

This article examines the debates in Israel between 2009 and 2013 over Iran’s nuclear programme as a reflection of a particular type of civil–military or civil–security relationship. It analyses how key actors within that relationship – particularly those with an intelligence background – engaged with media outlets in Israel and further afield to influence domestic and international opinion over how best to contain Iran’s nuclear ambitions. In so doing, it seeks to address one fundamental question: are governments in Jerusalem any longer the final arbiters over deciding what is in the national security interests of the State of Israel?     

应对混合战争的人防工程安检设施设置研究

冷战结束后,"混合战争"的威胁日益增加,人民防空工程和其他各类城市安全设施都亟需改进安全防护手段,增设安全检查设施,防控敌对势力的恐怖袭击和后方破坏.人防工程在战时对于出入口通行效率的要求远比地铁设施高,且出入口区域空间有限,无法照搬现有的地铁安检措施.本文从防范标准、安检流程以及技术手段等方面进行分析,提出运用新的检...

航空燃料水反应试验条件对试验结果的影响

航空燃料水反应试验是检测喷气燃料和航空汽油洁净性指标的一个重要方法,该方法的试验结果受试验条件影响.探讨了试验条件对试验结果的影响,通过考察摇动速率和摇动幅度,提出了优化摇动速率和摇动幅度的试验控制条件.在摇动时间为2min、摇动速率为150次/min、摇动幅度控制在185 mm、静置时间为5 min进行试验时,其试验结果均呈现很好的重复性和再现性,较好地消除了方法中试验条件控制对试验结果的影响.     

当前民用建筑防火设计有关问题探讨

结合工作实践,对《建筑设计防火规范》和《高层民用建筑设计防火规范》中关于民用建筑商业服务网点疏散及自动消防设施的确定、消防车道及其与建筑的距离、剪刀楼梯间的适用范围和正压送风系统、彩色镀锌钢板聚苯板夹芯板的使用问题、单元式住宅的安全出口及窗间墙宽度和窗槛墙高度的有关规定进行了重新分析探讨,并提出自己的建议和措施。     

地方物流资源动员研究

物流是将国民经济转化为军事战斗力的桥梁和纽带,是支援战争、保障军事行动胜利的重要前提。物流资源决定着物流能力的大小和物流水平的高低,而地方物流资源动员则决定着军事物流活动的效率和效果。从地方物流资源动员的内涵着手,分析了其重大意义,总结归纳了当前存在的突出问题,并就提高地方物流资源动员效益的方法举措进行了探析。     

美军陆航信息化能力建设之启示

陆航作为地面垂直力量的重要标志,是新时期军事变革的关键领域。美军以体制编制改革、主战平台建设为抓手,从机动作战、发现作战、打击作战、作战指挥、防护作战、保障作战等能力建设入手,迈出向目标部队转换的步伐,走在国际前沿。通过梳理美陆航在战略转型、平台规划、能力建设中的特点,从高速平台、无人平台、有人无人协同技术等方面对我新军事变革下陆航发展提供决策支撑。
