The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.  相似文献

The flow of international funds in real estate investment between Asian and North American cities in the Pacific Rim is now a major financial force to be recognized. This paper reviews the differences in the characteristics and performances of the real estate markets in Hong Kong, Singapore, and several west coast cities. The residential and office price movements among selected Pacific Rim cities over the last 20 years are compared. The paper attributes the differences in the performances to the differences in economic and planning policies in these cities, the differing strategies adopted by the market players, the differences in East and West cultural values, and the differing opportunities and risks created by the various "rules of the game" in each city. If Asian countries continue to enjoy robust economic growth, and the differences in regional real estate markets persist, the flow of international funds within the region and across the Pacific will continue to dominate the 1990's.  相似文献

在“双循环”背景下,加强“一带一路”建设对中国深化对外开放意义重大,促进中拉绿色贸易符合双方利益,可为“一带一路”延伸至拉美创造新的合作增长点。本文使用2002年至2018年的货物贸易数据,分析了中拉共建“一带一路”过程中中拉绿色产品贸易的特征和趋势,并重点研究了中国绿色产品对拉美的出口潜力。通过使用双边显示性比较优势指数和出口潜力矩阵,文章发现,在现有的中拉货物贸易结构中,绿色产品贸易所占比重较低,贸易对象高度集中,但随着双方经贸合作的全面深化、特别是“一带一路”延伸至拉美,双边绿色产品贸易金额和种类都在稳定上升。尽管中国绿色产品在拉美市场面临着地理距离遥远、市场竞争激烈等客观困难,但中国的优势产品已成功出口到拉美。中国的出口潜力更多地取决于拉美地区的市场需求,一旦拉美对绿色产品的需求提升,那么中国就具备进一步扩大向拉美出口该类产品的潜力。此外,出口潜力矩阵也找出了部分对拉美市场而言具备不可替代性的中国产品,这也将成为中国潜在的对拉出口重点绿色产品。  相似文献

Shortly after Hurricane Katrina's landfall in August 2005 and the reports of rampant looting of businesses in the city, we became curious about the extent of Katrina looting as compared to that after other major storms that hit New Orleans in 1947 and in 1965. Using burglary as a proxy variable for looting, we discovered that the burglary rates in the month before and the month after Katrina were significantly higher than those before and after the other two hurricanes. We then investigated the socioeconomic conditions in the city in an effort to explain these numbers. Population loss and high unemployment rates, coupled with a decline in high‐paying manufacturing jobs and an increase in low‐wage food and hotel service jobs generated severe economic inequality in the city that exacerbated the situation created by Katrina. Our current analysis of the impact of public school desegregation and the oil bust suggests that both events contributed to population loss and the increase in low‐wage jobs prior to the storm. We believe that this type of research can assist in the recovery of New Orleans by providing an understanding of the city's pre‐Katrina social and economic conditions and make clearer which post‐Katrina changes are desirable.  相似文献

A corporate strategy is often formulated on the executive floor at headquarters. However, in order to make it live in an organisation, middle management and employees must be involved and make sense of it. These actors thus contribute to, participate in and enact the strategy in processes where it may take on new meanings and forms. This article investigates how ‘Winning Behaviours’, a strategic concept developed on the initiative of top management at the Carlsberg Group in order to improve global integration in the multinational organisation, was recontextualised. It draws upon interviews and observations as well as documents collected at the company headquarters in Denmark and in its subsidiaries in China and Malaysia. Here, expatriate and local managers tried to give sense to the Winning Behaviours in various ways, and employees brought their own local leadership ideals into play when they tried to make sense of the preferred behaviours and turn them into daily practices. The process of creating a new strategic concept and making it live in other sociocultural contexts was facilitated by headquarters staff in the Human Resources and Communications departments, who thus played an important role as change agents in the ‘glocal’ strategy process.  相似文献

The mandate of the International Statistical Institute (ISI) is to foster international statistical work and interchange among statisticians and countries. However, women are under-represented in the ISI and this situation is a cause for concern in the Institute and its membership and particularly the ISI Committee on Women in Statistics (CWS). This paper analyses the representation of women in the ISI and in the statistics profession which is low in virtually every country, a pattern of generations. It looks at the diverse realities among countries and regions, and the broader context of women working in the scientific professions.  相似文献

ABSTRACT This paper examines the change in union wage differentials in Britain between 1984 and 1990, a period of considerable legislative change and marked decline in unionization. Small falls in union differentials are found for manual workers, together with a sharp decline in the premium associated with, and incidence of, the pre-entry closed shop. The decline in the average differentials is found to be largely due to the inability of unions to establish differentials in new establishments. No link is found between the differential and the probability of closure and no evidence of decline in raw differentials in a matched panel.  相似文献

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.  相似文献

The impact of the AIDS epidemic in developing countries, and in Africa in particular, is now a matter of great concern to policy makers, managers, and academics on a global scale. The magnitude of the potentially disastrous effects of the disease has severe implications for management in organizations, and, in particular, for HRM. The AIDS epidemic is imposing, and will continue to impose, in the foreseeable future, a significant burden on the way people are managed. Little has been written on HRM in Africa, and the present literature on AIDS and HRM in Western societies is inappropriate and insufficient in relation to African organizations. Fifteen organizations in Tanzania took part in this study, which is probably the first of its kind, to produce a picture of current developments and approaches in managing people under the threat of AIDS.  相似文献

We examine the behavior of stock market prices in several African countries by means of fractionally integrated techniques. In doing so, we can test for mean reversion in these markets. Our results can be summarized as follows: we cannot find evidence of mean reversion in any single market, and evidence of long memory returns (i.e., orders of integration above 1 in the logged stock prices) is obtained in the cases of Egypt and Nigeria, and, in a lesser extent in Tunisia, Morocco and Kenya. Permitting the existence of a structural change, the break dates take place in the earlier 2000s in the majority of the cases, and evidence of mean reversion seems to have taken place in the periods before the breaks in most of the countries. If we focus on the absolute and squared returns, evidence of long memory is obtained in Nigeria and Egypt. Thus, for these two countries, a long memory model incorporating positive fractional degrees of integration in both the level and the volatility process should be considered.  相似文献

This paper examines the formal and informal networks in small businesses in the media industry. Networks are important to small firms and are an integral part of the structure of the media industry. Technological changes and the proliferation of new channels have changed the nature of the television industry and this paper examines the role of networks in meeting these challenges. The research was based on questionnaires followed up with interviews. This study found that the social and cultural factors were important in the establishment and maintenance of both formal and informal networks. Low barriers to entry in terms of investment in fixed assets and powerful customers have meant that formal and informal networks play an important role in the survival and profitability of small firms in the media industry.  相似文献
