混沌消费者环境下的中国企业营销

进入21世纪,消费者的消费需求、购买特征、行为方式都表现出一定的复杂性与混沌性,消费者既是现实产品的消费者、也是虚拟世界的消费者。混沌的消费者环境不仅改变了企业的营销模式,也改变了企业的竞争方式。企业要应对混沌消费者环境下的竞争．需要采用新的营销模式．需要将水平营销、纵向营销聚合起来。     

ON THE SUSTAINABILITY OF COLLUSION IN A DIFFERENTIATED OLIGOPOLY WITH A CARTEL AND A FRINGE

We discuss the effects of the existence of non‐colluding (fringe) firms on cartel sustainability. We obtain, using trigger strategies, that with product differentiation collusion is always more easily sustained when firms compete in prices than when firms compete in quantities. This is true basically because (i) price competition is more intense than quantity competition, and (ii) fringe firms exacerbate the fact that cartel firms have more incentives to deviate from the agreement under quantity competition. This result reverses previous findings where, in the absence of fringe firms, product differentiation plays a crucial role in determining the effectiveness of price or quantity competition in sustaining collusion.     

向职工划转国有资产能缩小贫富差距吗--与吴敬琏先生商榷

面对贫富差距不断扩大的趋势,经济学家吴敬琏提出了"向国有企业职工划转国有资产"的观点.但是,这一解决方案是不可行的,它既忽视了贫富差距的主要矛盾,又缺乏最起码的公正、公平性,在实际中不具有可操作性,也无效率.此外,这一方案还会引起"寻租"、"创租"活动.因此,"向国有企业职工划转国有资产"无法解决不断扩大的贫富差距问题.     

论中国城市偏向的社会保障制度与城乡居民收入差距

中国城乡居民收入差距的形成与扩大和城市偏向的社会保障制度密切相关.城市偏向的社会保障制度反映在社会保障的模式、管理体制、覆盖面和水平等方面.这种城市偏向的社会保障制度增加了城镇居民的隐性收入,降低了农民抑制因灾致贫的能力,降低了农业劳动生产率,阻碍了计划生育政策的实施和农村劳动力素质的提高,从而最终导致了城乡居民收入差距的扩大.要缩小城乡居民收入差距,就必须改变城市偏向的社会保障制度,逐步建立城乡一体的社会保障制度.

劳动力析出对生态脆弱区耕地撂荒的影响

研究目的:以宁夏南部山区为例,研究农业劳动力析出对生态脆弱区耕地撂荒的影响。研究方法:二分类logistic回归模型。研究结果:撂荒耕地面积与劳动力外出数量、时间及农户所拥有的耕地总面积呈正相关;耕地中的坡耕地和旱地首先被撂荒。研究结论:劳动力析出会促使农户撂荒部分质量差的耕地;这种撂荒行为有助于生态环境的自然恢复。     

武汉市城乡结合部征地制度调查研究——基于农户与村级问卷调查

随着改革的不断深入，现行征地制度已明显滞后于市场经济的发展。本文以武汉市为例，对被征地农户进行了实地调查与分析，从征地类型的界定、农民的补偿安置、完善社会保障体系、加强法制监督等几个方面提出了完善征地制度的合理化建议。     

Endogenizing the Planning Horizon in Urban fringe agriculture

To evaluate the nature of farm operation longevity in urban fringe agriculture, this paper develops a model that endogenizes planning horizon and estimates an empirical model whereby anticipated longevity in farming is regressed against farm, farmer, regulatory and land market related variables. The results suggest that the length of the planning horizon is directly related to farm profitability and confirm the impermanence syndrome hypothesis that land values are inversely related to the planning horizon. Contrary to farmers’ claims that periodic land disposal provides an internal source of credit to support long-term viability, the disposition of portions of the farmland is found to shorten the planning horizon. Innovative farmers are found to have longer planning horizons while experiences with Right-to-Farm conflicts are found to result in decreased planning horizon. Given the expected continual increase in land values and the growing physical closeness of farmers to their non-farm neighbors, significant concerns remain about the long-term survivability of urban fringe farmers. This study suggests the importance of considering farmers’ planning horizon as a key component in farmland retention programs.     

What is the most suitable methodological approach to demarcate peri-urban areas? A systematic review of the literature

Unexceptionally all metropolitan areas throughout the world are surrounded by peri-urban areas that are neither urban nor rural in the conventional sense. Peri-urban areas are transition spaces, where the changes in different land uses are incessantly occurring. Determining the boundaries of these areas are critical to develop appropriate policies to manage and preserve them. The perpetual transition in peri-urban landscapes makes the boundary demarcation of these areas highly difficult. This paper aims to answer the question of what the most suitable methodological approach to demarcate peri-urban areas is. In order to address this question, the study undertakes a systematic review of the relevant literature. The findings show that a generic method does not exist to demarcate peri-urban areas as characteristics of peri-urban areas are not uniform across the globe. This paper advocates that techniques for peri-urban demarcation should be geographically specific, and in every case the regional and local contexts–e.g., political system, institutional arrangement, societal characteristic, environmental qualities, and economic drivers that underpin the peri-urban development—should be considered. The study provides insights to policymakers in order to determine peri-urban boundaries by tailoring available peri-urban demarcation techniques to their regional and local contexts.     

中国城乡关系演变60年:回顾与展望

新中国成立60年来,城乡关系经历了深刻变迁,城乡关系得到了很大程度的改善。当前,中国农业基础地位尚不稳固,缩小城乡居民收入差距任务艰巨,缩小城乡社会公共事业差距任重道远,城乡分割的二元结构尚未破除。加快建立平等和谐的城乡关系,需解决好农民土地权益如何有效保护、农业基础地位如何强化、信贷资金如何配置、农村富余劳动力如何转移、县域经济和小城镇如何发展壮大、新型农民如何培育等问题。
