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

Comparisons of agricultural productivity growth in China and India   总被引:1,自引:1,他引:0  
We measure and compare agricultural total factor productivity (TFP) growth and its components (efficiency and technical change) in China and India and test the TFP series for the existence of structural breaks relating the evolution of TFP to policy milestones. Our results show that agricultural TFP growth accelerates in China after 1979 and in India after 1974, although China’s agricultural sector clearly outperforms India’s. The main explanation of these differentials is that agricultural growth in China benefited from more fundamental institutional and policy reforms in agriculture than India. There is some evidence that the transformation of industry in China was also important for agricultural TFP growth. Manufacture growth absorbed labor and reduced employment in agriculture, creating incentives for capital investment and technical change that kept output per worker in agriculture growing at high rates. Fewer changes in agricultural policies and in the dynamics of manufacturing in India resulted in slower growth in agricultural productivity, despite policy changes that accelerated economic growth in recent years.  相似文献

The purpose of this article is to provide an overview on the state of research in the field in human resource management (HRM) issues in multinational corporations (MNCs) in and from China. We integrate previous studies from multiple disciplines to articulate the contextual importance of research on this topic, and suggest overarching themes to expand the field of research. HRM research in the intercultural, interinstitutional context of MNCs in and from China has the potential to provide contextualized insights for longstanding debates in the field such as HRM standardization versus localization and convergence versus divergence and contextual factors behind these patterns. To this end, we call for future research to center on the changing cultural, institutional, technological, and globalization context in understanding HRM and industrial relations issues in these MNCs. Practically, knowledge in this area can help global managers and top management teams in multinational organizations navigate various context complexity, foster more productive coordination and cooperation across borders, and gain legitimacy and MNCs in and from China additional competitive edge in the global marketplace.  相似文献

Knowledge flow in China’s humanities and social sciences   总被引:1,自引:0,他引:1  
Despite fruitful studies on knowledge flow and interdisciplinarity, there are few investigations on knowledge flow in humanities and social sciences (HSS) and how knowledge from science and technology diffuses to HSS sub-disciplines. Based on Chinese and English articles in HSS, this study explored knowledge flow in China’s HSS with an analysis of Chinese and English publications from 1998 to 2014. Findings include: (1) the interdisciplinarity degree of knowledge absorption in social sciences is higher than that of humanities in both Chinese and English articles, meanwhile the degree of interdisciplinarity in all HSS sub-disciplines increased constantly; (2) Chinese scholars in HSS increasingly tended to learn knowledge in hard sciences and applied it to their domains, especially in English articles; (3) in Chinese articles, Economics was the most crucial knowledge base, while Management, Education and Law were absorption-oriented sub-disciplines; in English articles Management, Law, Literature and Philosophy were absorption-oriented sub-disciplines.  相似文献

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

This article draws on the Organisational Growth and Development (OGD) life cycle model to explore the relationship between high‐performance work systems (HPWS) and performance in firms of different size, thereby extending understanding of congruence or ‘best fit’ theory within strategic HRM debates. With reference to management control theory, economies of scale and the availability of specialist managerial skills, the article hypothesises that while an HPWS–performance relationship might exist in small, medium‐sized and large firms, the relationship will be stronger in large firms than in both small and medium‐sized firms, and stronger in medium‐sized firms than in small firms. Analysis of data from the British Workplace Employment Relations Survey demonstrates, however, that there is no association between HPWS and workplace performance in medium‐sized firms, in contrast to the positive relationship between HPWS and performance found in large firms and between HPWS and labour productivity in small firms.  相似文献

The recent deregulation in electricity markets worldwide has heightened the importance of risk management in energy markets. Assessing Value-at-Risk (VaR) in electricity markets is arguably more difficult than in traditional financial markets because the distinctive features of the former result in a highly unusual distribution of returns—electricity returns are highly volatile, display seasonalities in both their mean and volatility, exhibit leverage effects and clustering in volatility, and feature extreme levels of skewness and kurtosis. With electricity applications in mind, this paper proposes a model that accommodates autoregression and weekly seasonals in both the conditional mean and conditional volatility of returns, as well as leverage effects via an EGARCH specification. In addition, extreme value theory (EVT) is adopted to explicitly model the tails of the return distribution. Compared to a number of other parametric models and simple historical simulation based approaches, the proposed EVT-based model performs well in forecasting out-of-sample VaR. In addition, statistical tests show that the proposed model provides appropriate interval coverage in both unconditional and, more importantly, conditional contexts. Overall, the results are encouraging in suggesting that the proposed EVT-based model is a useful technique in forecasting VaR in electricity markets.  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

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

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

abstract    This paper presents a set of theoretical propositions regarding knowledge sharing in China and Russia. We argue that there are important national cultural similarities and differences between the two countries that result in certain similarities and differences in individual knowledge-sharing behaviour in Chinese and Russian organizations. We claim that vertical collectivism and particularistic social relations in China and Russia lead to intensive social relations among organizational members, which facilitate knowledge sharing between in-group members in organizations in both countries. We also maintain that differences in the essence of collectivism as well as in the extent of collectivism in the two cultural contexts lead to different intensities of knowledge sharing in Chinese and Russian organizations. Finally, we discuss theoretical and management implications of this research.  相似文献
