Their per-unit cost does not decrease but increase with the growth of such projects product size. Thus this is diseconomies of scale that occur in them. The significance of this phenomenon results from the fact that it is commonly considered to be one of the fundamental objective causes of their low effectiveness. This is of particular significance with regard to Business Software Systems （BSS） D＆EP characterized by exceptionally low effectiveness comparing to other software D＆EP. Thus the paper aims at answering the following two questions： （1） Do economies of scale really not occur in BSS D＆EP？ （2） If economies of scale may occur in BSS D＆EP, what factors are then promoting them？ These issues classify into economics problems of software engineering research and practice.展开更多

Hence, in order to achieve the object, the study analyzes the status quo of economic development in Tibet and the problems of resource exploitation. It especially discusses frailty of Tibetan eco-environment, and evaluates the contradictions between the traditional economic developing mode and the safety of plateau＇s ecosystem. It concludes that there is an inevitable clash between the development of Tibetan economy and the safety of plateau＇s eco-system; this problem cannot be avoided by any decision maker, Therefore, the character of Tibetan econvironment and the requirement of its economic development strategy determine that ecological economy developing mode is the only choice for Tibet. This paper suggests that it should be compensated by the national government to assure that Tibetan economy can keep a higher developing speed. In accordance with the feature of plateau eco-economy system and demand of Tibetan economic development, this paper also suggests several methods to apply the ecoeconomy developing strategy of Tibet.展开更多

Circular economy is a kind of complicated economic activity, and it is a wholly new ecotype economy proposed by Western countries after they had summed up many experiences and lessons from traditional economy. It is an entirety and has many layers. It keeps an open and dynamic balance. Because the system theory is the theoretical foundation of circular economy, we should systemically analyze and study circular economy from the macroscopic view, correctly grasp its operational laws, improve its service functions, and realize human beings' sustainable development. The paper introduces the content and general characteristics of the system theory and the idea of circular economy. Then it analyzes circular economy based on the system theory. The paper concludes that the integration of circular economy and the system theory can promote the functions of circular economy.展开更多
文摘This paper identifies three stages in China's agricultural development with reference to macroeconomic development and international experience.While the first two stages focused on ensuring food security and raising farmer's income,the current stage must give priority to modernizing agricultural production.The lack of progress in this area is due to the following reasons:diminishing return to capital as a result of small and scattered farming operation which has compromised agricultural competitiveness;agriculture is overdependent on subsidy and protection under the conventional wisdom of the uniqueness of agriculture.This paper attempts to reveal the barriers to China s agricultural modernization and proposes recommendations on reforming the land and household registration systems to increase the economies of scale and productivity.
