The development of the semiconductor industry depends on its interactions with the environment. Developing countries face more constraints and the environmental interactions seem more complicated. The development process of the semiconductor industry could be better understood with regard to the interactions and social changes. This study proposes a variety-increasing viewpoint based on the concepts of variety increasing and internal learning to analyze the developmental experience of the semiconductor industry in Taiwan. The result shows that the development of Taiwanese semiconductor industry is a continuous variety-increasing process, which is achieved by searching and establishing successful associations in an increasingly wider and complex environment. Implications on the ongoing development of Taiwan's semiconductor industry and the development experiences of other East Asian countries are discussed. 相似文献

一般理论认为,按生产要素分配主要体现在非公有制领域和公有制领域内劳动者收入来源的多样性上.但事实上,随着我国劳动力市场的发展和完善,按生产要素分配在公有制领域内将有更大的作用空间.其具体实现形式之一,即为公有制范围内劳动收入由V+Vm构成,而且对企业利润(M)中分配后的剩余部分,仍可实行按生产要素分配,而后者是建立国有资产保值增值机制的一种新思路. 相似文献

Summary. This research studies the role of multivariate distribution structures on random asset returns in determining the optimal
allocation vector for an expected utility maximizer. All our conclusions pertain for the set of risk averters. By carefully
disturbing symmetry in the distribution of the, possibly covarying, returns, we ascertain the ordinal structure of the optimized
allocation vector. Rank order of allocations is also established when a permutation symmetric random vector is mapped into
the returns vector through location and scale shifts. It is shown that increased dispersion in the vectors of location and
scale parameters benefit, ex-ante, investors as does a decrease in the rank correlation coefficient between the location and
scale parameter vectors. Revealed preference comparative static results are identified for the location and scale vectors
of asset returns. For most issues addressed, we arrive at much stronger inferences when a safe asset is available.

根据弹性稳定理论,对当量弯矩折减系数Cm的计算公式的应用范围作了进一步说明,并确定了其应用范围.同时,考虑砼偏心受压构件的弹塑性性能,推导了新的公式,与原有的公式比较,具有同样的精确度,由于考虑了砼材料的变形模量,因此其结果更接近实际. 相似文献

This paper examines the influence of economic integration—widening of the trading area—on economic development and the demographic transition. Economies produce with different technologies depending on their scale. Greater integration between regions (greater extensive scale) is instrumental in changing rates of return, which generates an industrial revolution and provokes changes in child bearing behavior. The demographic transition follows from the mortality response to income and birth response to greater scale. The model is calibrated and simulated using historical data from Europe. Historical evidence is cited to support the idea that integration precedes the dramatic rise in economic growth rates. 相似文献

For some non–parametric testing problems (one–sided two–sample problem, k –sample trend problem, testing independence against positive dependence) a partial ordering, denoted by ≥, over the alternatives is defined. This partial ordering expresses the strength of the deviation from the null–hypothesis. All familiar rank tests turn out to become more powerful under "increasing" alternatives; that is, all familiar rank statistics preserve the ordering stochastically in samples whenever it is present between underlying distributions. As a tool, the sample equivalence of ≥ is introduced as a partial ordering over pairs of permutations. Functions, defined on pairs of permutations, which preserve this ordering are studied. 相似文献

The recent applied production theory literature focusing on the economic performance of firms has increasingly recognized the importance of scale effects on costs and therefore efficiency. These scale effects may include short run returns due to fixity of privately demanded inputs (i.e., capital, long run internal returns to scale, and external factors affecting costs. Since these different types of scale effects can be thought of as shifts in and movements along cost curves, the different cost effects of such factors can be identified in a framework which explicitly takes them into account in the definition ofscale.In this article we formalize such a framework, and then use it to measure short run, long run (internal) and external scale effects from fixity of private capital, nonconstant returns to scale and public infrastructure. We then use these measures to identify the impacts of these different scale factors on productivity growth. The focus on public infrastructure as an important external scale factor is motivated by the current theoretical and policy interest in this issue; we show how a structural production theory model provides a rich basis for the analysis of the cost effects of infrastructure investment. 相似文献

通过对我国改革开放以来GDP增速、煤炭消费增速历史数据的分析,发现不管是经济发展,还是煤炭发展过程中都存在周期性的波动变化规律。而通过对煤炭与经济波动曲线的拟合,发现煤炭与经济发展呈协同波动变化。基于以上煤炭与经济协同波动规律,对未来煤炭与经济发展走势进行了推演,发现煤炭消费增速最早要在2015年前后才能企稳提高,由此进入新一轮上升期。综合分析表明,煤炭抗波动能力较弱,未来要实现煤炭平稳发展,需根据经济发展节奏的不断变化,及时主动地调整煤炭发展步伐,从而避免因煤炭发展的冒进或硬着陆给煤炭及关联产业发展带来长时间、高强度的冲击和损害。 相似文献
