This article investigates the impact of digital technology diffusion on the productivity of firms making up the local operating sector of the U.S. telecommunications industry for the years 1991 to 1993. Diffusion of digital technology is measured as the extent of line digitalization that has taken place, with digitalization expected to enable firms to reap significant operating efficiencies. While the diffusion of this particular technology in the local operating company sector has been relatively low, it is found that, after controlling for the effects of a number of other covariates also likely to affect firm-level performance, the spread of digital technology within the U.S. local telephone network plays a significant and positive role in impacting productive efficiency of the firms making up the network. The investments that have been made in energizing the U.S. information superhighway, via the digitalization of telephone lines, are justified in productive efficiency terms. The article contributes to empirical literature in the technical change area which assesses the firm-level productive efficiency consequences of technology diffusion. 相似文献

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings. 相似文献

Social entrepreneurship has emerged as an active area of practice and research within the last three decades. Nevertheless, in spite of its growing popularity, scholars and practitioners are far from reaching a consensus as to what social entrepreneurship actually means. This has resulted in a number of different definitions and approaches within the field of social entrepreneurship. The purpose of this article is to shed light on the ongoing contestation of social entrepreneurship and to offer a novel conceptual understanding of the concept that can facilitate the development of systematic and structured future research. To this end, we analyze social entrepreneurship on the basis of the theory of essentially contested concepts, which was proposed by Walter Bryce Gallie in 1956. Building upon this theory, this article shows that social entrepreneurship can be regarded as an essentially contested concept and that a universal definition that would be accepted among contestant parties is hardly possible. Responding to this recognition, the article proposes the conceptualization of social entrepreneurship as a cluster concept, which can serve as a conceptual tool to help advancing social entrepreneurship as a coherent field of research despite its contested nature. 相似文献

Entrepreneurs of small organisations describe growth differently. Growth strategy of these organisations is a function of industry structure and performance, entrepreneurial motivation, attitude, and competence of the entrepreneurs in strategy planning. The article based on Grounded Theory approach is an attempt in developing a theoretical framework on growth strategy planning in small entrepreneurial organisations. Two major patterns are emerging. In ‘relationship based strategy’ entrepreneurial vision towards strengthening relationship is the basis for growth planning. Trust, cooperation, community and society benefit are important dimensions. In ‘technology based strategy’ the entrepreneurs choose technology to achieve excellence in product and process performance, and need investment and risk bearing capability. 相似文献

This article evaluates the impact of broadband adoption on wage and employment levels among the local exchange companies in the US telecommunications industry for the period between 1988 and 2001. Broadband is a general purpose technology and its adoption and diffusion is expected positively to impact wages because of the need for higher level skill in its deployment and usage, but can also lead to less human capital usage because of a scale effect. Using the extent of fiber adoption among the local exchange firms as a measure of broadband deployment, it was found that broadband diffusion within and between the firms over time has had a positive and significant impact on wage levels but its impact on employment has been negative. As broadband diffusion increases, with substantial scope available to do so given the low levels of deployment both among the local exchange firms studied and within the United States as a whole, the impact of such diffusion on enhancing wage levels in the sector can be profound. 相似文献

The issue of resource utilization is important in the resource-based stream of work, since the ability of firms to utilize resources is a key indicator of their competitive abilities. This paper specifies why some firms might be better at utilizing resources than others. Thereafter, it demonstrates how to empirically ascertain differences in resource utilization patterns between firms using the U.S. telecommunications industry as a context. The data envelopment analysis procedure (DEA), which is a firm-level resource utilization measure, is used. This procedure can be useful for the resource-based approach research agenda since performance is measured in resource terms. DEA is applied to measure variations in different dimensions of resource utilization for the firms making up the local operating sector of the telecommunications industry. The use of DEA to guide empirical research and address theoretical issues within the resource-based paradigm is illustrated, using the resource utilization index for the telecommunications firms as the measure of strategic performance. © 1998 John Wiley & Sons, Ltd. 相似文献

This analysis evaluates the impact of corporate debt in influencing mergers of local exchange companies in the United States telecommunications industry between 1988 and 2001. Firms’ financial structures significantly affect behavior and performance; yet no evidence has shown how firms’ financial structures influence their merger activities. The impact of corporate debt levels on the various mergers that took place during the merger wave in the sector is significantly negative for the first set of mergers carried out, and significantly negative, but with smaller impact, for the second set of mergers. The results support the idea that firms with high debt levels can be monitored carefully, precluding engagement in potentially-risky mergers so as to not engender negative financial outcomes. 相似文献
