新疆石河子垦区发展循环经济的几点思考

发展地域循环经济是实现可持续发展的现实选择,是走新兴工业化道路的重要途径,也是解决地域经济发展瓶颈的关键。本文结合新疆石河子垦区自然、社会经济条件,提出必须通过垦区经济结构与布局调整大力发展循环经济,建立垦区循环经济发展格局,并通过多种途径培育循环经济发展条件。     

科学发展观与马克思学派社会经济分析大思路——社会经济科学分析模型的建立与中国适用

社会经济发展理论源于斯密和李嘉图为代表的古典经济学派,是二战后在发达国家广泛流行的理论,其理论及模型的建立强调科学技术进步、人力资本积累、劳动分工以及制度变迁的作用。但发达国家理论家自身存在的认识论缺陷使其不可能科学完整地建立社会经济发展理论及分析模型。因此必须遵循马克思的方法论从理论为实际的反映人手,建立科学的社会经济发展理论,并以此指导和服务于社会经济发展的实践。     

共享经济视域下的军事训练场地整合

军改以来,"军委管总、战区主战、军种主建"的格局打破了原有军事训练场地的建设、管理和使用模式,训练场地需求旺盛,缺口较大,急需构建适应新体制新机制的新型训练场地建设管理体系,满足训练需求。本文分析了当前军事训练场地建设管理中存在的问题,提出了基于共享经济模式整合军事训练场地资源的对策措施。     

SECURITY BRIEF

Using crime review figures for four randomly selected states in Nigeria, this study examines cases of kidnapping and its implications for the national economy. The findings reveal that kidnapping is consistently on the increase in Nigeria and is not evenly spread across regions. It is shown that 15 cases were recorded in 2005 and 43 cases in 2008. In 2009, 138 cases were officially recorded, of which 22% and 76% occurred in Rivers and Edo states respectively. Findings further showed that modern kidnapping in Nigeria is triggered by resource control disputes directed both at oil expatriate workers and at prominent citizens, politicians and members of their families. The crisis, which came to the fore in 2005, has forced oil production shutdowns of up to 800 000 barrels per day. The study concludes that kidnapping is becoming a serious crime in Nigeria with significant negative implications for foreign investment, national foreign exchange earnings, and revenue generation.     

ECONOMIC SANCTIONS AND CULTURE

We address empirically the question of why international economic sanctions are, or are not, chosen as instruments of foreign policy and the question of what determines their success. We hypothesize that cultural linkages between nations are an important factor in explaining both instrument choice and conflict outcomes. Countries that share significant cultural attributes are found to be less likely to apply economic sanctions against one another than countries lacking such cultural ties. However, it is precisely in the case of culturally similar sender and target nations that sanctions are most likely to succeed.     

Revenue management under randomly evolving economic conditions

We consider a dynamic pricing model in which the instantaneous rate of the demand arrival process is dependent on not only the current price charged by the concerned firm, but also the present state of the world. While reflecting the current economic condition, the state evolves in a Markovian fashion. This model represents the real‐life situation in which the sales season is relatively long compared to the fast pace at which the outside environment changes. We establish the value of being better informed on the state of the world. When reasonable monotonicity conditions are met, we show that better present economic conditions will lead to higher prices. Our computational study is partially calibrated with real data. It demonstrates that the benefit of heeding varying economic conditions is on par with the value of embracing randomness in the demand process. © 2015 Wiley Periodicals, Inc.

循环经济与可持续发展

循环经济和知识经济并称为21世纪发展新亮点,也是世纪之交人类社会可持续发展的两大趋势。人类社会在经历了漫长的发展历史之后,正处于一种大量的资源、能量的耗费,大量的废物进入生存环境的状态,自然环境一次又一次向人类敲响警钟。本文试从循环经济这一视角来对其与可持续发展的问题进行探讨。
