文化传统与秦国农业的发展——中国传统文化软实力研究之一

秦国农业发展成就的取得与其文化传统密切相关。关中地区"好稼穑、务本业"的社会风尚奠定了秦国农业发展的文化基础;秦文化重功利的价值取向使秦国的农业激励政策发挥出了最大效能;宗法观念淡薄则使个体小家庭生产这种最适应生产力发展水平的经营方式在秦国得到了最彻底的推行。     

Why members stay in or leave an R&D consortium: performance and conditions of membership as determinants of continuity

This paper jointly examines performance and conditions surrounding membership as determinants of the decision to stay or leave an R&D consortium. Hypotheses were developed for performance and, by drawing from power dependence and transaction cost theories, for conditions surrounding membership. Analysis of survey questionnaire data from 184 member organizations of U.S.-based R&D consortia indicates that performance and the conditions of knowledge-related involvement, network ties, learning, and alternatives are related to the decision to stay in or leave. These results provide limited support for power dependence but are more consistent with transaction cost theory. Subsequent analyses revealed an interaction between performance and membership conditions, suggesting performance leads to the conditions of membership, and that the continuity decision for a poorly performing consortium differs from that for one performing well. © 1997 John Wiley & Sons, Ltd.     

Power, conflict, and cooperation: The impact of guanxi in Chinese marketing channels

This paper tests the impact of guanxi on behaviors among firms in a Chinese marketing channel. Guanxi is operationalized in this paper as emotional closeness and interactive state. We find that the emotional closeness between channel-boundary personnel of firms has a positive impact on their exercise of noncoercive power, a negative impact on their exercise of coercive power, and a negative impact on the perceived conflict between them. In addition, emotional closeness has an indirect but positive impact on perceived cooperation. Interactive state between the boundary personnel of two firms has a positive impact on a firm exercising noncoercive power and a negative impact on perceived conflict between them. At the same time, it is positively related to a firm exercising coercive power. This shows not only the significant influence of guanxi on a firm's channel behaviors but also the constructive effects of both emotional closeness and interactive state on marketing channel behaviors in China.     

基于并联FIR滤波器组的Hammerstein预失真器

采用预失真技术对功率放大器的记忆非线性失真进行补偿的关键是预失真器建模的准确性,尤其是模型对功率放大器逆记忆特性的描述能力。针对目前预失真器模型对功率放大器逆记忆效应描述不充分的问题,提出了将查找表(LUT)级联一个具有并联结构的有限长单位冲激响应(FIR)滤波器组作为实现形式的Hammerstein预失真器,以提高传统Hammerstein预失真器的补偿性能,并采用一种两步算法对其参数进行辨识。仿真实验表明,提出的Hammerstein预失真器能更好地补偿带强记忆效应的功率放大器的非线性失真。     

The Governance of Networks and Economic Power: The Nature and Impact of Subcontracting Relationships

Abstract.  Current debate on networking focuses on network structures and firm strategies. In this perspective, theoretical analysis has been concerned with allocative issues. This essay proposes a different interpretation. Starting from the existing theoretical framework, we emphasise the nature and the implications of different types of networks with respect to socio‐economic development from a distributional point of view. Within this context, we develop the analysis of subcontracting starting from the concept of economic power. We then provide an analysis of governance in production by considering the attitudes and the nature of the actors involved. The externalisation of activities by large transnationals, which characterises current corporate restructuring, is often related to the search for greater flexibility, but also for greater power over governments, labour, and subcontractors. Differently, networks based on the mutual dependence of actors, which are not necessarily built around a large firm, could – under particular conditions – reach large production scales or more complex scopes without breaking the links with territorial systems, thus including local objectives in the strategic decision‐making process. Our conclusion is that the impact of subcontracting networks varies enormously. This is crucial to an understanding of future trends and possibilities. Not least, firms and public policy agencies need to understand the implications of different forms of subcontracting network and how those forms actually differ in practice.     

Power politics and the expansion of US exports, 1879–1938

In this article, we present quantitative evidence for the first time of the effect of US power politics on the expansion of its export market from the late nineteenth century to the eve of the Second World War. Like other empires, US imperial policy was expressed through annexation, gunboat policies, and asymmetrical trade agreements. We find that US exports to territories that became colonies or protectorates and those involved in other US military interventions grew more than three times faster between 1880–5 and 1934–8 than in the rest of the world. Our most relevant contribution to this discussion relies on a new geographically extensive database with information on bilateral trade flows, market size, trade costs, and variables that capture US political and military power. We first estimate a gravity equation to see the relationship between our power politics variables and US exports. Then, we present causal evidence of the role played by the colonies and protectorates in the expansion of US exports through an event study and the estimation of a generalized difference-in-differences model.     

土地产权三维界定的技术路线及其评论

研究目的：对已有研究文献涉及土地产权三维界定的技术路线进行结构性把握,梳理研究脉络与趋势,以期为土地产权三维界定在研究方法和范式上的改进提供思路。研究方法：文献分析法、比较分析法。研究结果：从理论基础、界定起点和界定方案看,国内外学界对土地产权三维界定大致存在三条技术路线：基于空间分离原理的技术路线、基于空间区分原理的技术路线和基于三维地籍原理的技术路线,分别反映了法学和地籍学对土地产权形态和产权客体进行三维界定的技术方案。研究结论：未来应将土地产权形态与产权客体三维界定统一起来,厘清其内在逻辑与生成路径,深化三维土地产权客体特定化实现机制、国家公权力植入三维土地产权实现机制和三维土地产权排他性支配机制研究,加快构建三维土地产权范式。
