We examine the relationship between return and volatility of the stock markets and macroeconomic fundamentals for the G-7 countries by using monthly data ranging from July 1985 to June 2015. To meet this end, we apply the spillover index approach based on the generalized VAR framework developed by Diebold and Yilmaz (2012, 2014). The empirical analysis shows strong interactions between the returns and volatilities of the G-7 stock markets and the considered set of corresponding macroeconomic factors including industrial production, money supply, interest rates, inflation, oil prices and exchange rates. The return and volatility spillover transmission/reception dynamics of the relationships between these stock markets and the macroeconomic fundamentals have changed after the global financial crisis of 2008. Our findings provide useful insights for investors and policy makers concerned with the unprecedented swings in the stock markets of G-7 countries. 展开更多

In the new normal,China must develop a new economy in order to foster new engines of growth.The new economy differs from the traditional economy in many respects,such as its underlying drivers and technical,industrial and organizational characteristics.This paper reveals six aspects of the mechanism of the new economy,including firm entry strategy,new opportunities,market demand,transition of production factors,industry support and the role of the government.In addition,the operation of the new economy is explained in terms of its underlying drivers,internal operations and external environment.In the new economy,fundamental changes have occurred in monopoly,information asymmetry,externalities,public goods and information security necessitating a new regulatory approach.Regulatory reform is therefore inevitable.China should steadfastly transition from regulatory tightening to deregulation,from economic regulation to social regulation,from discriminatory regulation to fair competition,from the positive list to the negative list,from ex-ante review and approval to ex-post supervision,and from specialized regulation to integrated regulation.Innovations must be encouraged through the use of “regulatory sandboxes.” 展开更多

Mobile news apps have emerged as a significant means for learning about latest news and trends. However, in light of numerous news apps and information overload, motivating users to adopt one app is a major concern for both the industry and academia. Therefore, considering the attributes of mobile news and the debate on switching costs in the Internet context, based on the expectation-confirmation model (ECM), this study suggests that switching costs still exist and have a significant moderating effect on user satisfaction and continuous usage of mobile news apps. Furthermore, the different influences of information quality, system quality and service quality on continuance intention, user satisfaction and switching costs are discussed, showing that quality of information has a significant impact on users’ continuous usage of mobile news apps through increasing perceived usefulness, whereas personalized service quality have stronger effects through increasing user satisfaction and switching costs. 展开更多

The export status to Japan is directly related to the overall trend of China’s agricultural exports. Based on the HS9-coded agricultural product trade data of the Japanese Ministry of Finance in 2001-2017,using the ternary marginal analysis method,the driving force of China’s agricultural exports to Japan was analyzed in this paper from a static and dynamic perspective. The results showed that 98. 89% of the driving force of China’s agricultural exports to Japan was from the contribution of quantity margin. The contribution of the extensive margin had been decreasing year by year after 2006,and it has been negative for many years. The reason was that technical barriers such as the Positive List System lead to less export of agricultural product in varieties and types. The average marginal contribution rate of price was 8. 26%. The average price of exported agricultural products has been basically higher than the world average level since 2013,suggesting that the quality of exported agricultural products has been improved. While maintaining the quantity of agricultural exports,improving the quality of agricultural products,expanding export varieties and increasing export value added are the sources of sustainable growth of China’s agricultural exports in the future. 展开更多

In the literature on the migrant phenomenon in China, homeownership, city integration, and sense of happiness have all been examined, yet the synergetic relationship among these three factors has not been fully discussed. This study uses the 2012 National Dynamic Monitoring Database of Migrants created by the National Health and Family Planning Commission of China to explore the cooperative relationship between migrants, homeownership, city in teg ration and the sense of happiness. Generally, renting houses reduces migrants/ sense of happiness. However, with migrantsz greater integration into the place to which they have migrated, the sense of happiness of migrants who live in rental houses is enhanced to a greater degree than those who live in their own houses. This phenomenon is clear among migrants who have moved from less developed regions to developed regions and among those who have moved relatively longer geographical distances. This study demonstrates a city integration mechanism through which homeownership influences migrants' sense of happiness. We con tribute to happiness economics research and propose a scientific basis for speeding up new urbanization as well as improving a housing system which encourages both house renting and purchasing in China. 展开更多

Although exploration and exploitation, as a pair of paradoxical organizational outcomes, are generated by different causal conditions, the conjunction of their respective causal antecedents has yet to be fully examined. Combining environmental uncertainty, unit interdependence, entrepreneurial bricolage and firm life cycle stage in a qualitative comparative analysis (QCA), the distinct causal configurations of exploration and exploitation are formalized and compared based on a survey of founders or high-level managers in 63 small firms. Results show that contrasted relationships between entrepreneurial bricolage and unit interdependenee exist in that the two antecedents are partial substitutes in exploration whereas they are complements in exploitation when combined with other conditions. This study provides empirical evidence on the causal configurations of exploration and exploitation and deepens our current understanding of ambidexterity. 展开更多

Using the multidimensional poverty index(MPI),this paper measures the intertemporal change in poverty in China’s rural areas during 1995-2013,decomposes major poverty reduction factors,and creates a correlation between poverty reduction factors and national pro-farmer and poverty reduction policies.Our findings suggest that multidimensional poverty has been greatly alleviated in rural China on all fronts beyond the income dimension.Specifically,the burden of out-of-pocket medical expenses contributed the most to the overall poverty of farmers in the 1990s;this gap was subsequently mitigated by the New Rural Cooperative Medical Insurance System.Lack of economic empowerment-the second most prominent manifestation of poverty two decades ago-has been alleviated with public welfare improvements.In the present stage,health and healthcare are the primary difficulties facing poor farmers multidimensionally.Sub-groups such as elders,those less educated and those living in western China or in poor counties suffer from a high degree of poverty.This implies that multidimensional poverty is concentrated among the underprivileged groups and in less developed regions,whom should be policy priorities.Robustness tests suggest that the paper’s conclusion still holds after changing the proxy variables of the subdimensions,revising weights or removing some dimensions. 展开更多

This paper employs difference-in-differences(DID)approach to evaluate the effects of China’s Labor Contract Law’s implementation on rural migrant workers’welfare.Our findings suggest that the Labor Contract Law has reduced rural migrant workers’ working hours by 23%,and increased their social insurance coverage by 10% to 26%.This conclusion holds true after removal of sample selection bias and policy expectation factor.Further analysis reveals that Labor Contract Law’s welfare improvement effect was more significant for migrant workers in regions where workers had poor bargaining power.Other economic factors during the same period of time did not affect the law’s labor protection effect.Our findings give a clear answer to controversies over whether the Labor Contract Law can improve labor rights for underprivileged groups,and are of reference value for developing labor protection systems. 展开更多

It is important to identify and remove the wastes not only from manufacturing process, but also from nonmanufacturing process. In the last several decades, significant research achievements and practice benefits have been achieved about removing wastes from manufacturing process. Since the1990 s, some researchers and lean practitioners have paid more attention to removing waste from non-manufacturing process.Based on the authors’ research work and industrial practice, the paper introduces a kind of lean approach for removing waste from non-manufacturing process. In its case study, the order handling process in a value chain is described with respect to a factory and its downstream distribution centers(DCs). The paper proposes a lean approach solution for creating the improved order handling process, and analyze how great improvements in performance can be achieved. As a result, the significant achievement has created a win-win scenario for both the nonmanufacturing process in a factory and non-manufacturing facilities(like DCs) across the value chain. It demonstrates that improvements have been made by removing waste from the non-manufacturing process that takes place within a factory as well as with external participants through the whole value chain. Likewise, the proposed lean approach has helped the case companies to achieve greater levels of efficiency and more benefits. Finally, some conclusions are drawn. 展开更多

Controversies exist in literature regarding what indicators should be employed to measure China’s fiscal decentralization.This paper measures China’s fiscal decentralization by the sharing ratios of county-level VAT and corporate income tax(CIT).This approach avoids such problems as homogeneous denominator,and reflects the intricate interactions between governments at different levels.Based on extensive sources including the National Fiscal Statistical Information at Prefecture and County Levels and China County(City)Socio-Economic Statistical Yearbook over the 1998-2007 period,our estimation and analysis led to the following findings:(1)Since 2002,counties have retained a falling share of revenues;(2)a multidimensional horizontal comparison reveals a pattern in the county-level tax sharing ratio,i.e.counties in central and eastern regions retain a higher share of tax revenues compared with those in western and northwestern regions.These findings explain the fiscal difficulties at the grassroots level,and can be used to conduct a quantitative analysis of the determinants and economic effects of China’s fiscal decentralization.” 展开更多

Service computing is an emerging and distributed computing mode in cloud service systems, and has become an interesting research direction for both academia and industry. Note that the cloud service systems always display new characteristics, such as stochasticity, large scale, loose coupling, concurrency non-homogeneity and heterogeneity;thus their load balancing investigation has been more interesting, difficult and challenging until now. By using resource management and job scheduling, this paper proposes an integrated, real-time and dynamic control mechanism for large-scale cloud service systems and their load balancing through combining supermarket models with not only work stealing models but also scheduling of public reserved resource. To this end, this paper provides a novel stochastic model with weak interactions by means of nonlinear Markov processes. To overcome theoretical difficulties growing out of the state explosion in high-dimensional stochastic systems, this paper applies the mean-field theory to develop a macro computational technique in terms of an infinite-dimensional system of mean-field equations. Furthermore, this paper proves the asymptotic independence of the large-scale cloud service system, and show how to compute the fixed point by virtue of an infinite-dimensional system of nonlinear equations. Based on the fixed point, this paper provides effective numerical computation for performance analysis of this system under a high approximate precision. Therefore, we hope that the methodology and results given in this paper can be applicable to the study of more general large-scale cloud service systems. 展开更多

Based on the Fisher–Yatess scrambling and DNA coding technology, a chaotical image encryption method is proposed. First, the SHA-3 algorithm is used to calculate the hash value of the initial password, which is used as the initial value of the chaotic system. Second, the chaotic sequence and Fisher–Yatess scrambling are used to scramble the plaintext,and a sorting scrambling algorithm is used for secondary scrambling. Then, the chaotic sequence and DNA coding rules are used to change the plaintext pixel values, which makes the ciphertext more random and resistant to attacks, and thus ensures that the encrypted ciphertext is more secure. Finally, we add plaintext statistics for pixel-level diffusion to ensure plaintext sensitivity. The experimental results and security analysis show that the new algorithm has a good encryption effect and speed, and can also resist common attacks. 展开更多

By studying an admissible family of branching mechanisms{ψt,t ∈E} introduced in Li [Ann. Probab., 42, 41-79(2014)], we construct a decreasing Levy-CRT-valued process {Tt, t ∈ E} by pruning Lévy trees accordingly such that for each t ∈E, Tt is a ψt-Lévy tree. We also obtain an analogous process {Tt*,t ∈E} by pruning a critical Levy tree conditioned to be infinite. Under a regular condition on the admissible family of branching mechanisms, we show that the law of {Tt,t ∈E} at the ascension time A := inf{t ∈E;Tt is finite} can be represented by{Tt*,t∈E}.The results generalize those studied in Abraham and Delmas [Ann.

Traditionally,small and medium enterprises(SMEs)in manufacturing rely heavily on a skilled,technical and professional workforce to increase productivity and remain globally competitive.Crowdsourcing offers an opportunity for SMEs to get access to online communities who may provide requested services such as generating design ideas or problem solutions.However,there are some barriers preventing them from adopting crowdsourcing into their product design and development(PDD)practice.In this paper,we provide a literature review of key crowdsourcing technologies including crowdsourcing platforms and tools,crowdsourcing frameworks,and techniques in terms of open call generation,rewarding,crowd qualification for working,organization structure of crowds,solution evaluation,workflow and quality control and indicate the challenges of integrating crowdsourcing with a PDD process.We also explore the necessary techniques and tools to support the crowdsourcing PDD process.Finally,we propose some key guidelines for coping with the aforementioned challenges in the crowdsourcing PDD process. 展开更多

The key argument of this conceptual paper is that the roots of a viable future for an organisation are found in a robust strategic architecture perspective.The theoretical baselines for the concepts associated with this paper are linked to a variety of strategy theories.These include,but are not restricted to,institutional theory,strategic thinking relating to the positioning-based view(PBV)and resource-based view(RBV)respectively,entrepreneurial thinking,and innovation thinking.Strategy can be described as the collective,emerging pattern—based on strategic choices—an organisation consciously exhibits and executes over time to ensure its sustainable endurance by differentiating itself in unique ways to create and add value for stakeholders.Strategy is about explaining how an organisation wants to move forward and how it wants to advance the interests of stakeholders.A strategic landscape is the broad external and internal context of an organisation.An important part of strategy and the strategic landscape it operates in is how organisations define or“construct”their own“topography”or strategic architecture.A strategic architecture presents an organisation?s core logic for creating sustainable value,and therefore,forms the foundation of an organisation?s competitive potential in a specific context.This paper presents descriptions of the seven key buildings blocks that constitute a strategic architecture perspective for an organisation with an indication of strategy tools and frameworks that can be used to illuminate strategic possibilities,choices,and challenges to assist ongoing strategising praxis.The key features and assumptions associated with a strategic architecture perspective are discussed.A strategic architecture perspective assists leaders to work through the strategic complexity to arrive at simplicity in the form of clarity on external and internal strategic leverages,strategic aspirations,core strategic choices,plausible multiple scenarios,focused strategic goals,and success measurements t 展开更多

This study aims to contribute to marketing theory by applying monopolistic competition theory to investigate how differentiation affects online retailers7 pricing power. We examine the intermediary effect of customer loyalty on the relationship between differentiation and pricing power of online retailers. We assume that customers have different preferences for the differentiated characteristics of online retailers, and thus different degrees of willingness to pay premiums, which gives online retailers pricing power. Structural equation modeling (SEM) is employed to test the hypothesized relati on ships between differentiation, customer loyalty, and pricing power. The statistical results of the empirical data indicate that some of the differentiation characteristics of online retailers can cultivate their pricing power indirectly. Logistics quality followed by commodity assortment and transaction security produces profound effects on the buildup of pricing power with customer loyalty as an intermediary factor. Results further reveal that commodity quality is positively related to pricing power. This study expands the definition of differentiation by combining corporate strategic positioning with commodity pricing. Implications for practice and di recti ons for future research are provided. 展开更多
