Small and medium-sized companies are increasingly facing international markets as part of their processes of growth and development. A great deal of literature deals with different patterns of growth and international development that are specific to SMEs with respect to large companies. Fewer studies have been conducted on the reconfiguration of company supplier relationships involved in these processes. This paper focuses on the role played by the consolidated set of company supplier relationships when the firm faces some critical stages in its process of development, i.e., growth from small to mid-sized and the implementation of new ventures abroad accessing new business relationships with international suppliers. A multiple and longitudinal case study shows how the local set of supplier relationships of four mid-sized Italian mechanical companies acting in industrial districts has played an important role in shaping the emerging set of supplier relationships and addressing companies' actions in their growth and internationalization processes.  相似文献

A baseline model of industry evolution   总被引:10,自引:2,他引:10  
The paper analyses some general dynamic properties of industries characterized by heterogeneous firms and continuing stochastic entry.After a brief critical assessment of some significant drawbacks of recent contributions to modeling of stochastic industrial dynamics, we propose a novel analytical apparatus able to derive some generic properties of the underlying competition process combining persistent technological heterogeneity, differential growth of individual firms and turnover. The basic model, we suggest, is indeed applicable with proper modifications to a large class of evolutionary processes, well beyond industrial dynamics.JEL Classification: L11, O30, C60Support to this research by the International Institute for Applied Systems Analysis (IIASA), Austria; the Fujitsu Research Institute for Advanced Information (FRI), Japan; the Italian National Research Council (CNR), the Italian Ministry of Education, University and Research (MIUR, prot. 2002132413 003) and the Free University of Bozen Bolzano, Italy, is gratefully acknowledged. Comments by Andrea Bassanini, Francesca Chiaromonte, Steven Klepper, Uwe Cantner, Drew Fudenberg and the anonymous referees helped in shaping the paper to its present form. Mariele Berté provided the computer simulations of the model. The usual caveats apply.Correspondence to: G. Dosi  相似文献

Most developing countries achieved necessary critical technology quickly and efficiently through the offset channel. Taiwanese government procurement is one of the most important sources of technological development. Over the past 10 years, this performance has not been remarkable in obtaining improved rising defense technology using the offset (namely, Industrial Cooperation Program, ICP). The main objective of this paper is to discuss the problems with Taiwan's ICP and propose a four-stage approach for Taiwan's ICP mechanism detailed improvements are suggested for Stage I and Stage II. F-16 fighter coproduction was used as an example to simulate Stages I and II in the four-stage approach process, considering all three levels of technology, economics and national security, to establish a set of fuzzy multiple criteria decision mode to identify the evaluative criteria variables and project item's order for ICP project. This decision mode was identified as a workable method.  相似文献

引领科技发展的新创知识虽然是未来经济社会发展的动力源泉,但由于缺乏市场的长期检验,这类新创知识早期应用成本和风险均较高,导致集群企业很难主动接受。文章在相关文献综述的基础上,阐释了集群知识系统运行的基本假设,构建了一个基于传染病模型的政府参与的集群知识扩散模型,通过数理推导发现,无论产业集群内现存知识的传播再生数多大,政府宏观调控和激励政策在集群内新创知识推广和应用过程中的作用显著,能够加快集群内知识系统的跨越式升级,最后文章提出了促进集群内新创知识应用的政策建议。  相似文献

1. Introduction The area of carbonate rocks protruding through the soil level in China is 9.07*105km2. According to the area of carbonate rocks stratum protruding through the soil level, it is 2.06*106km2. With the buried carbonate rocks stratum of the different depths, its total area can reach 3.443*106km2, ap- proximately accounting for 1/3 of the national terri- torial area. Chinese carbonate rock is mainly distributed to the south of the latitude belt of Tianshan Mountain – Yinshan Moun…  相似文献

A sizeable percentage of investors are using social media to obtain information about companies (Cogent Research [2008]). As a consequence, social media content about firms may have an impact on stock prices (Hachman [2011]). Various studies utilize social media content to forecast stock market-related factors such as returns, volatility, or trading volume. The objective of this article is to investigate whether a bidirectional intraday relationship between stock returns and volatility and tweets exists. The study analyzed 150,180 minute-by-minute stock price and tweet data for the 30 stocks in the Dow Jones Industrial Average over a random 13-day interval from June 2 to June 18, 2014 using a BEKK-MVGARCH methodology. Findings indicate that 87% of stock returns are influenced by lagged innovations of the tweets data, but there is little evidence to support that the direction is reciprocal, with only 7% of tweets being influenced by lagged innovations of the stock returns. Results further show that the lagged innovations from 40 percent of stock returns affect the current conditional volatility of the tweets, while 73 percent of tweets affect the current conditional volatility of stock returns. Moreover, there is strong evidence to suggest that the volatility originating from the returns to the tweets persists for 33 percent of stocks; the volatility originating from the tweets to the returns persists for 73 percent of stocks. Last, 53 percent of stocks exhibit both immediate and persistent impacts from returns to tweets, while 90 percent of stocks exhibit both immediate and persistent impacts from tweets to returns. These results may help traders achieve superior returns by buying and selling individual stocks or options. Also, asset and mutual fund managers may benefit by developing a social media strategy.  相似文献

Industrial research in the United States took hold and grew during much of the 20th century. Bell Labs, a corporate component of the Bell System, was perhaps the premier example. The period from 1925, when Bell Labs was formed, to 1984, when the Bell System was broken up following a government antitrust lawsuit, is of special interest because the system operated as a regulated monopoly during that period. Telephone subscribers effectively paid for research and development in their monthly phone bills, which provided an element of financial stability for the labs. Statistics research was one of many types that thrived, much to the benefit of the Bell System, its customers, and the science of statistics. The purpose of this article is to review, explain, and illustrate the circumstances that contributed to this success and to raise the question of how modern corporations, operating in fully competitive environments, might achieve some of the same benefits.  相似文献
