This paper examines how Chinese agribusiness firms are engaging with established systems of private governance in the Brazilian soybean sector and how that engagement is variously accommodated, contested, and configured by local realities that reflect the uneven history of transnational agribusiness development across the Brazilian agro‐export region. Using qualitative data collected at three research sites that represent different historical moments in the Brazilian agro‐export region (Mato Grosso, Goiás, and Bahia), the paper argues that the social structures underlying the particular agrarian histories of these three subregions create unique contexts Chinese firms must navigate, which in turn shapes their engagement with the private agribusiness regime across space. Although the private agribusiness regime is often portrayed as a top‐down system of governance that subjugates the polity to the demands of capital, this framing neglects to understand how that system of power is contested, negotiated, and reshaped on the ground. These three cases serve to historicize the uneven penetration of Chinese firms across the Brazilian soybean sector.  相似文献

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement.  相似文献

20世纪50—60年代既是新中国财政学初建时期,也见证了苏联财政学传统移入和退出的过程。就其理论和实践来源看,苏联财政学是苏联化的马克思主义、苏联特殊年代政治实践和计划经济体制等诸多因素的混合物。虽然它在发展和创新马克思主义财政理论方面作出了首创性的贡献,但其历史局限性也不可避免。在苏联财政学移植中国之时,其中一些负面特征也参与了新中国财政学的重建,并对其后中国财政学的发展起到了长久的羁绊作用。20世纪50年代后期以来,中国财政学“去苏联化”的目标未能完全实现,这一方面源于塑造苏联财政学的思维模式仍然在当时的中国财政学界起着支配作用;另一方面在那些影响财政学发展的主要因素上,当时的中苏两国极为雷同。吸取20世纪50年代中国移植苏联财政学的历史经验和教训,对当下中国合理借鉴域外学术资源、发展和创新马克思主义财政理论,有着重要的借鉴意义。  相似文献

In this study, we examine the effects of four demographic factors, namely, birth, death, natural aging, and net migration, on population aging and income inequality in China. We use the official Chinese data and the China Household Income Project Survey data for the 2007–2013 period and apply a decomposition model based on the Shapley method. Unlike previous studies, we include migration in our decomposition model and find that natural aging is the primary factor contributing to population aging in both urban and rural areas. Further, migration may accelerate population aging in rural areas. Moreover, migration contributes to reducing income inequality in urban areas, while widening income inequality in rural areas. The effect of migration is larger than those of birth, death, and natural aging on income inequality. The robustness checks confirm these conclusions.  相似文献

China has made significant progress in broadband development. As of September 2018, 95% of China's population was covered by 4G networks. However, our estimates show that nearly 30% of China's families did not use broadband that year. This study attempts to investigate the characteristics of China's broadband left-behind families. Overall, consistent with the findings for other countries, families with a lower socioeconomic status are more likely to be broadband non-adopters. In the information society, older, poorer, rural and less educated families are left behind. It is recommended that the Chinese government shift from a top-down investment-driven policy to a user-centered demand-driven policy to address the digital divide.  相似文献

We investigate the effects of the 2008 New Zealand (NZ)–China free trade agreement (FTA) on exports from NZ to China, and real GDP per capita in NZ using the synthetic control method to estimate the counterfactuals. NZ exports to China were more than 200% higher in 2014 than what they would have had the FTA never been signed. NZ's food and live animals exports to China were more than 180% higher in 2014 than the counterfactual. Our counterfactuals indicate a small but negative effect of the FTA on NZ's real GDP per capita between 2009 and 2012.  相似文献

This study examines the links among corporate social responsibility (CSR), reputation, and performance in hotel companies from a multidimensional perspective. Data were collected from 322 hotels in China and partial least squares equation modelling (PLS-SEM) was employed for a causal-predictive analysis. Study results reveal that CSR practices influence hotel reputation as seen from both international and local perspectives. CSR and reputation influence performance dimensions (accounting-based performance, market-based performance, and non-financial performance) differently. The research findings offer specific theoretical and practical implications for hotel managers.  相似文献

We assess the conditional relationship in the time-frequency domain between the return on S&P 500 and confirmed cases and deaths by COVID-19 in Hubei, China, countries with record deaths and the world, for the period from January 29 to June 30, 2020. Methodologically, we follow Aguiar-Conraria et al. (2018), by using partial coherencies, phase-difference diagrams, and gains. We also perform a parametric test for Granger-causality in quantiles developed by Troster (2018). We find that short-term cycles of deaths in Italy in the first days of March, and soon afterwards, cycles of deaths in the world are able to lead out-of-phase US stock market. We find that low frequency cycles of the US market index in the first half of April are useful to anticipate in an anti-phasic way the cycles of deaths in the US. We also explore sectoral contagion, based on dissimilarities, Granger causality and partial coherencies between S&P sector indices. Our findings, such as the strategic role of the energy sector, which first reacted to the pandemic, or the evidence about predictability of the Telecom cycles, are useful to tell the history of the pass-through of this recent health crises across the sectors of the US economy.  相似文献

ABSTRACT

Multinationals (MNCs) have been considered a relevant research topic for International Relations since the emergence of the field of International Political Economy in the 1970s. Nowadays, MNCs are undergoing deep changes in their business models and global strategies due to the digital economy. This has considerable implications for the international system. For instance, the rise of information and communication technology (ICT) MNCs to the top of market value lists globally. Nonetheless, IR scholars have been slow in grasping the importance of ICT MNCs and the digital economy. In this paper, I justify this statement by evaluating the inclusion of MNCs and ICT MNCs in Brazilian IR scholarship. The method used is a bibliometric mapping of the scientific production of Brazilian IR scholars, supported by a systematic literature review. The results showcase that, in spite of the impact of digitalization on Brazil's economy and politics, IR scholars have conducted few studies on MNCs and practically no studies on ICT MNCs. This case illustrates the emergence of new dynamics in global value chains triggered by digitalization. It also illustrates the challenges for developing countries such as Brazil to engage in global production networks within the highly competitive ICT sector.  相似文献

新冠疫情冲击了世界经济增长和金融市场稳定。很多国家推出极度宽松货币政策应对危机。从经典货币政策国际协调的博弈理论来看,应对本次疫情冲击的各国货币政策协调性不足,“以邻为壑”的非合作均衡效果明显。为数不多的货币政策协调也存在执行力不足、深度与广度不够、新兴市场国家话语权低等问题。在世界经济紧密联系、货币政策溢出效应加强的背景下,为了应对疫情冲击,国际组织需要创设协议和合作剩余分配机制,寻找货币政策刺激效果和防止国际资产泡沫之间的平衡,加强政策沟通和信息共享,提高新兴市场国家话语权,建设有效的应对危机的货币政策国际协调机制。中国应在“一带一路”倡议的框架下建立长期货币政策协调机制,在现有的IMF和G20等平台上发挥发达国家与新兴市场国家之间的协调桥梁作用,通过持续开展央行间技术性合作等措施参与和推进协调进程。  相似文献
