循环经济的生态学基础探究

循环经济本质上是一种生态经济,生态学是其重要的学科基础.已有文献论述了循环经济的若干生态学原理,文章从以下几个方面予以补充:(1)循环再生原理:从有限到无限的生命法则; (2)进化与演替:发展循环经济必须以文化、社会的深刻变革为依托; (3)主导性与多样性原理:主导性和多样性的合理匹配才能维持系统的稳定与持续; (4)自生原理:合理利用和维护自然系统的自生机制,保证经济与社会发展的可持续性.     

Changing Perspectives on the Factors of Production

Envy is a complex emotion that influences the behavior of envious and envied individuals. Because envy can imply ill will, discontent or dislike of the envied individual who possesses something that the envious individual desires, or aspiration to emulate the envied position, it can lead the envious individual to undertake costly efforts to reduce the gap between the envied situation and his own situation. The envious individual can seek either to damage or match the situation enjoyed by the envied individual. In return, the envied individual can adopt either envy-appeasing strategies or envy-arousing strategies. We argue that these costly envy-related behaviors impede or stimulate economic development.

Size (and competition) among organizations: modeling scale‐based selection among automobile producers in four major countries, 1885–1981

Based on previous empirical research, size is perhaps the most powerful explanatory organizational covariate in strategic analysis. We suggest that theoretical arguments about size be examined carefully to specify models with explicit comparison sets and with mechanisms linking size and underlying processes to outcomes. We illustrate the approach here by advancing arguments about scale competition within an organizational population. In this effort, we feature a theoretical model of scale‐based selection, which posits that a firm's chances of survival decrease with its aggregate distance from larger competitors on a transformed size gradient. The model assumes that the appropriate comparison set consists of all contemporaneous similar organizations competing on the basis of scale and operating in a localized geographic setting. We argue that aggregate distance of a focal firm from larger other firms (a specific form of relative position in the size distribution) reflects the extent to which it can capitalize on potential competitive advantages of scale emanating from economic, political, and social processes. Analyzing the mortality rates of large organizations across the entire histories of automobile industries in four major countries provides support for the theory. We discuss the general implications of our findings for strategic and organizational analysis. Copyright © 2003 John Wiley & Sons, Ltd.     

生态节能旅游景区设计的若干关键性技术探索

随着我国经济的不断前进,我国的旅游产业和房地产业在近几年得到迅猛发展,将旅游与地产相结合形成的系统性理论与实践,逐渐成为越来越多的学者研究的重点。而现在旅游景区的建设多是资源依托型,其建筑更是消耗能源的主要方面,已经不适合社会可持续发展的要求。文章结合生态旅游及绿色建筑的理念,相互渗透,相互融合,在研究两个理论的发展状况和趋势的基础上,通过秦皇岛生态节能示范区的建设实践,比较其与普通景区的节能优势,重点落实于关键性节能技术的探索和总结。将绿色建筑的思想应用于旅游景区的规划设计中,不仅是生态旅游发展的内在需要,也是广泛推广绿色建筑,实现经济效益和社会效益统一的根本体现。
