Manufacturing profitability and growth declined sharply in Canada between 1955 and 1984. The spatial extent of this decline has not previously been documented. This article examines manufacturing performance in six regions of Canada. The analysis reveals significant interregional performance differences that appear to be increasing. Two different types of inter-firm competition are identified in the article: competition in production and competition in the market. Empirical investigation reveals that changes in production conditions had a greater impact on regional profitability in five of the six regions studied. In the remaining region, poor market performance was the primary cause of the reduction in profits after 1955.
Au Canada la rentabilité et la croissance industrielle ont profondément diminué entre les années 1955 et 1984. L'ampleur spatiale de cette baisse n'a jamais été docu-mentée. Cette étude examine le comportement et les performances de fabrication dans six régions canadien-nes. De considérables différences inter-régionales, qui semblent toujours s'accentuer sont mises en évidence. Dans cette recherche, deux genres de concurrence entre les societes son identifiés: la concurrence dans la production, et la concurrence dans le marché. L'analyse empi-rique montre que certains changements dans les conditions de production ont eu un effet considérable sur la rentabilité régionale pour cinq des six régions en question. En ce qui concerne la dernière région, la baisse des profits a partir de 1955 est dûe essentiellement à la mauvaise performance du marché.  相似文献

Over the last decade, but particularly since 1984 when the fourth Labour Government came to power, New Zealand has become something of an experimental test bed for the implementation of monetarist ideas of political and economic management. A noticeable outcome of the policy regime recently put in place has been a dramatic ‘opening up’ of the economy as markets are deregulated, protection barriers lowered, and restrictions on movement of capital in and out of the country removed One consequence has been a quantitative and qualitative change in the internationalisation of the economy. This paper traces the nature and extent of this process, and speculates on some policy implications. Four key dimensions of the internationalisation process are surveyed: the expansion of New Zealand capital off-shore, increased levels of foreign investment in New Zealand, the impact of reductions in border protection, and closer economic relations between Australia and New Zealand.  相似文献

Critical physical geography (CPG) calls for integrative research on material landscapes and the socio-political dynamics of scientific knowledge production. Network analysis, a rich tradition of tools and approaches for analyzing relational information, has seen little use in the CPG literature to date. This represents a fruitful opportunity, as many of CPG's core interests—knowledge politics, histories of scientific concepts, and ecosocial relations—can be effectively analyzed using network techniques. In this article, I argue for adapting network approaches to CPG. First, I provide an overview of various network concepts, approaches, and their origins. I then discuss bibliometric network techniques for “science mapping” including co-word, co-authorship, and citation analyses. Next, I describe discourse network analysis, a recent mixed-method approach from political science. Finally, I discuss overlaps with emerging approaches from qualitative and visual network analysis. In each section, I provide existing and hypothetical examples, as well as software and visualization techniques, that demonstrate how network approaches could add new insights to CPG and related scholarship. Linking CPG with the diverse traditions of network analysis has the potential to produce new empirical understandings and bring the field into conversation with a growing body of research that spans the social sciences, natural sciences, and humanities.  相似文献

This paper examines James Buchanan's normative theory of the state and in particular his attempt to establish a legitimating linkage between the individual and the state. It begins by outlining Buchanan's consent‐based theory of the state and the distinction he draws between the explanatory and justificatory roles of his theory. It proceeds to examine the role of his conceptual contract as a justificatory argument for existing and proposed political institutions. It finds that while the conceptual contract may provide an account of the contingent rationality of the state, it fails to have normative significance in terms of Buchanan's value individualism and subjectivism. Buchanan has also failed to address some of the problems associated with securing and enforcing contractual agreement. These conclusions point to wider problems with rational choice theories of the emergence of the state.  相似文献
