《中国新时期学术热点研究》是一部在中国当代学术史研究方面具有开创性、探索性的著作。该书就中国新时期学术发展史的3个阶段做了简要回顾,对学术腐败的现象进行了概括陈述,就学术界、管理界对学术规范、整治学术腐败等方面相应的对策也进行了探析。以学人来论述学问的个案论析,是其又一特点。     

广州市镇域物流业的发展特征与模式——以花东镇为例

区域物流产业是区域经济的重要组成部分,也是现代城镇经济形成与发展过程中不可或缺的一部分。本文以广州市花东镇为例,通过实地调研、GIS可视化及问卷调查法对该镇物流企业的发展特征和模式进行分析。研究发现,花东镇的物流企业目前存在产业关联性不强、物流企业集聚效应有限、企业对外联系较少等问题。在此基础上,根据其特征归纳出镇域物流业的三种发展模式,即政府主导物流园区发展模式、机场带动发展模式和跨国公司带动发展模式。     

论跨域治理多元主体间伙伴关系的构建

当代社会公共事务和公共问题日渐增多,错综复杂的跨域公共问题大量出现。面对大量跨区域、跨部门、跨领域的社会公共事务,仅仅依靠地方政府这个治理主体难以解决,需要运用跨域治理理论,多元主体之间构建伙伴关系,共同进行有效的治理。本文以湖北省梁子湖水污染防治为例,阐明为了有效应对跨域公共问题,需要跨域治理多元主体之间构建伙伴关系,并提出了建立伙伴关系的具体路径。     

Theories of Reason in China and the West: From the Point of View of the Enlightenment

A conception of enlightenment that is new in both origin and prototype yet rooted in Chinese tradition can be found in the works of Liang Shuming and Zhu Qianzhi, his follower in the historical field. Kant maintained that enlightenment implied that the power of reason would give man the courage to use his mind. Similarly, Zhu Qianzhi used enlightenment to define reason, putting the focus of enlightenment on religion. In doing so, on the one hand, he neglected the richness, complexity and inner evolution of the Western concept of reason; on the other hand, like Hegel, he dismissed the subtle but significant differences between Chinese and Western concepts of reason. In terms of thought, intuition, emotion, desire, practice, skill and the movements of nature, reason in the Western tradition inevitably tends toward the good. The word later used to translate “reason” into Chinese had already appeared in Confucian and Buddhist classics. Reason in Song and Ming Confucianism is an all- embracing absolute; its function involves intuition, thought and emotion, all directed toward the good. Liang Shuming accepted the differentiation between reason and understanding of Western philosophy, but proposed that understanding was the function and reason the essence of the heart-mind. Overall, this represents only the heart-mind approach. The non- religious character, didactic tendency and emphasis on intuition in the Confucian view of reason can all be found in the Confucian theory of emotion. Being essentially a response to good and evil, emotion may share some common ground with classical Western philosophy.     

土地承包经营权流转内涵界定研究

目前,理论上和实践中对土地承包经营权流转内涵重要理论问题学界尚未达成共识,存在以"保留(土地)承包权、转移土地经营权(土地使用权)"、"转移(或者让渡)部分或者全部土地承包经营权"、"土地承包经营权的变动"等为实质内容或依据界定土地承包经营权流转内涵的不同观点,其内容差异大,且都存在明显不足.统一采用法定的"土地承包经营权流转"名称是界定其内涵的关键.依据土地承包经营权流转包括物权性质土地承包经营权让渡型流转和物权性质土地承包经营权保留型流转这一客观事实,应以"移转(或者转移)物权性质土地承包经营权或者物权性质土地承包经营权中的部分权能"为实质内容界定土地承包经营权流转内涵.     

Balancing Revenues and Repair Costs under Partial Information about Product Reliability

We consider the problem faced by a company selling a product with warranty and under partial information about the product reliability. The product can fail from multiple failure types, each of which is associated with an inherently different repair cost. If the product fails within the warranty duration, then the company is required to pay the repair cost. The company does not know the probabilities associated with different failure types, but it learns the failure probabilities as sales occur and failure information is accumulated. If the failure probabilities turn out to be too high and it becomes costly to fulfill the warranty coverage, then the company may decide to stop selling the product, possibly replacing it with a more reliable alternative. The objective is to decide if and when to stop. By formulating the problem as a dynamic program with Bayesian learning, we establish structural properties of the optimal policy. Since computing the optimal policy is intractable due to the high dimensional state space, we propose two approximation methods. The first method is based on decomposing the problem by failure types and it provides upper bounds on the value functions. The second method provides lower bounds on the value functions and it is based on a deterministic approximation. Computational experiments indicate that the policy from the first method provides noticeable benefits, especially when it is difficult to form good estimates of the failure probabilities quickly.     

农民工对城市本地劳动力的就业替代模型及其实证分析

文章运用微观经济学理论,在阐释农民工进城的替代效应的基础上,探索构建了两类劳动力替代关系的计量模型,并利用2000年人口普查资料进行实证分析。结果表明,中国城市中被农民工替代的岗位数占城市本地劳动力的7.2%,占农民工总量的33.6%;农民工与城市本地劳动力之间高度互补、小幅替代,并且不同性别、受教育程度、职业间的替代程度存在显著差异,劳动力市场分割严重。     

农民工社会养老保险:政策评估与制度创新

农民工处于城镇化的最前沿,但基本处于无保障或低保障的状态。从与城镇职工养老保险制度的关系角度出发,业已实行的农民工社会养老保险政策可归纳为农保模式、城保模式、双低模式、综合保险模式等。本文在对这4种模式分析和评估的基础上,建议为农民工建立新的制度模式和运行体系,并创造性地设计出具有“基本结构因年龄制宜,缴费及待遇低进低出,管理方式灵活方便”特点的“个人账户与集体账户弹性结合”的新型农民工养老保险制度。
