Emerging market multinationals (EMNEs);entry mode;outward foreign direct investment (OFDI)
摘要:
A significant number of studies explore outward foreign direct investment (OFDI) by emerging market multinationals (EMNEs) mainly focussing on the rationale for and the evolution of such investments. It is not clear if the entry mode patterns established in studies on developed economy multinationals (DMNEs) are valid for EMNEs. This study assesses the literature on entry mode by EMNEs by volume of output by major academic disciplines, the evolution of the number of papers in the area, the theoretical underpinnings of the papers, the methodologies used in studies and the number of emerging economies that have been investigated. The review suggests that there is a need for research in this area especially by academic disciplines other than international business and area studies, and for studies to be extended to cover a larger range of emerging economies. It also suggests that the theoretical underpinning for such studies needs to be developed. © 2022 Denfar Transnational Development INC.

摘要:
To estimate the dynamic trend of industrial water-waste-energy (hereinafter referred to as WWE) system, this paper proposes a new method for forecasting specific indicators in such a system. First, the fractional accumulated generation operator, fractional derivative and classic nonlinear grey Bernoulli model are simultaneously coupled to develop an optimised nonlinear grey Bernoulli model that identifies the nonlinear trends in industrial WWE systems. Second, the particle swarm optimization algorithm is employed to determine the optimal model parameters in the newly-designed model. Based on this, simulation studies are conducted to examine the stability of the proposed model. Finally, the model is applied in the industrial WWE system. The results demonstrate that (1) the proposed model outperforms other competitive models in terms of error-value metrics and (2) industrial water use and industrial energy consumption will increase, whereas industrial wastewater discharge will decline. Furthermore, the rationality of the predicted results redis analyzed from a policy perspective. © The Author(s) 2022.

摘要:
The "Air Pollution Prevention and Control Action Plan" is regarded as China's war against air pollution, which is also noted as China's Clean Air Action (CAA policy). Although abundant studies have focused on the impact of CAA policy on social activities, such as air quality, pollutants emission, and economic output, limited studies explore its impact on enterprise competitiveness from a more micro perspective. Improving total factor productivity (TFP) is essential to achieve economic efficiency and sustainable development. Identifying the impact and influence mechanism of the CAA policy on TFP is important for China to realize the coordinated development of environment and economy and promote high-quality economic development. Based on the difference-in-differences model, this paper evaluates the impact of the CAA policy on enterprise productivity. The empirical analysis shows that there is a significantly negative effect from the CAA policy to the TFP of polluting enterprises, indicating that the CAA policy has decreased enterprise productivity. Our finding is robust, after conducting several robustness tests, such as replacing different dependent indicators, adopting different policy measurement variables, considering other policy interventions and using propensity score matching. Besides, this paper also discusses the possible heterogeneities. This paper adds additional empirical evidence to understand the relationship between air pollution control and enterprise competitiveness. The conclusions of this paper have important practical significance for China to further promote air pollution control and perfect the environmental control system.

摘要:
Carbon dioxide is believed widely to be the major contributor to global warming. Policy-makers worldwide are turning to tax policies in an effort to abate carbon emissions. China is the largest emitter of carbon emissions on our planet. The central government, as well as the local official, has introduced a series of environmental regulations, such as environmental protection tax and emissions trading system, to reduce carbon emissions and improve environmental quality. In the near future, the carbon emission tax is also expected to be implemented by the Chinese government. In order to analyze and predict the effect of the carbon emission tax on environmental and economic systems, we developed a four department dynamic stochastic general equilibrium model, which includes households, enterprises, the government, and the environment. The dynamic parameters were obtained using maximum likelihood estimation. In the comparative static-s analysis, we found that after the introduction of carbon emission tax, the level in environmental quality was substantially improved, whereas most economic variables were significantly reduced. Moreover, we used impulse responses functions to evaluate how one shock to the carbon emission tax affects the steady static values for these endogenous variables in our model. We found that the carbon emission tax shock has an instantaneous effect on the majority of economic variables, but it does not affect the environmental quality immediately. In addition, we tested the Porter hypothesis and found no evidence suggesting the statement regarding this hypothesis. Finally, we applied Bayesian estimation to assure our findings in this study, again. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

摘要:
Abstract: The safety behavior of vocational school students is worth noting. The current study is aimed to examine the effect of self-control demands on safety behavior. Drawing on the Self-Control Resource Model, we predict that self-control demands have a negative effect on safety behavior through ego depletion and perceived teacher support moderates the link among self-control demands, ego depletion, and safety behavior. A two-wave survey was conducted and 285 vocational students participated in our study. Mediation and moderated mediation modeling analyses were carried out. Results showed that ego depletion fully mediated the link between self-control demands and safety behavior. Moreover, perceived teacher support moderated the relationship between self-control demands, ego depletion and safety behavior; for students who perceived high levels of teacher support, the negative effect of self-control demands on safety behavior via ego depletion was insignificant, while for students who perceived low levels of teacher support, their negative effect was significant. The present study clarifies the effects of self-control demands on safety behavior through the resource depletion process and highlights the importance of teacher support in buffering the negative effect of self-control demands on workplace safety. Enhancing safety management, engaging in a resource recovery activity, and providing teacher support training are effective ways to maintain high levels of workplace safety.

摘要:
This study uses a group of specially treated stocks to examine the effect of daily price limits in the Chinese stock market. We show that lower price limits significantly reduce liquidity and widen spreads. These results remain consistent when using difference-in-differences regressions with propensity score matching and after conducting regression discontinuity analyses. The findings are more prominent for firms experiencing lower-limit hits, with higher disclosure quality and lower probability of informed trading before the limit changes. These findings suggest that restrictive price limits cause unexpected behaviour of informed traders, enhance information asymmetry, reduce stock liquidity, and hinder price discovery process. © 2022 Accounting and Finance Association of Australia and New Zealand.

摘要:
In view of the problem of excessive noise in financial time series, this paper proposes a nearest neighbor dynamic time warping classification method for financial time series based on the optimal smooth denoising model (osdDTW2). First, the optimal smooth denoising model is improved, and then the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) method is used to decompose the time series signal. Then, the improved optimal smooth denoising model is used to construct a low-pass filter to do the denoising of the time series. After being denoised, the time series are aligned by dynamic time warping (DTW), Finally, the nearest neighbor method is used for classification. This paper also uses the UCR datasets to verify the effectiveness of the proposed method and applies it method to financial time series classification. The experimental results suggest that osdDTW2 (αsm=0.9) can improve the effectivness of the benchmark algorithm (DTW) to some extent. © 2022 World Scientific Publishing Company.

Discrete grey forecasting models;Ill-condition;Multiplicative transformation;Weakened fractional-order accumulation operator
摘要:
In this study, the weakened fractional-order accumulation operator for alleviating the ill-condition of discrete grey system models with the aim of improving the grey system theory is proposed. It is found that the weakened fractional-order accumulation operator composed of the improved fractional-order accumulation operator and the multiplicative transformation can not only alleviate the ill-condition of the system by decreasing the differences between the elements of the columns (rows) in the coefficient matrix but also further enhance the prediction performance of the models. Therefore, the weakened fractional-order accumulation operator is an effective improvement measure. The demonstration of the unbiasedness and affine transformation property of the discrete grey forecasting models with the weakened fractional-order accumulation operator further strengthens the theoretical basis of this new system. Two real-world time series are used as cases to demonstrate the effectiveness of the discrete grey system models with the weakened fractional-order accumulation operator compared with discrete grey forecasting models based on five other different accumulation operators(1-order accumulation operation, new information accumulation operation, fractional-order accumulation operator, damping accumulative generating operator and the conformable fractional-order accumulation operator). The results of the comparative analysis show that the proposed weakened fractional order accumulation operator can not only substantially reduce the ill-condition of the models but also have good predictive performance, both of which confirm the feasibility and validity of the method. © 2022 Elsevier Inc.

摘要:
已实现极差波动率(RRV)极大地弱化了微观结构噪音的影响,比已实现波动率(RV)的有效性更高。但目前主流的HAR-RRV-跳跃模型忽略了符号变差成分在预测中的差异。由于RRV在跳-扩散框架下是有偏的,难以进行符号分解。因此通过刻度校正及校正分解的方法,分别推导了RRV符号连续和符号跳跃成分。同时,考虑到外部信息冲击也会导致RRV不同方向的非对称变化,利用LGARCH模拟这种非对称影响,构造兼顾符号变差与外部信息冲击的HAR-SRRV-CJ-LGARCH模型和HAR-SRRV-SCJ-LGARCH模型。以沪深300和中证500指数1分钟高频数据作为研究样本,采用多种损失函数和MCS检验评价模型预测能力,结果显示:在预测中考虑了符号变差成分并利用LGARCH模拟外部信息冲击,可以明显提升模型预测能力,同时引入符号连续及符号跳跃的HAR-SRRV-SCJ-LGARCH模型在平稳期和短期预测中最优。

摘要:
The establishment of the Xiong'an New Area has been an important decision for China to remove noncapital functions. This paper will use the Xiong'an New Area policy as a quasi-natural experiment and will use the synthetic control and difference-in-difference (DID) methods to study the influence of the establishment of the Xiong'an New Area on the quantity and prices in the new and secondhand housing markets in Beijing. This paper found that after the Xiong'an New Area was established, the overall quantity of new houses in Beijing decreased and the quantity of secondhand houses first increased and then decreased. The price of new housing increased steadily and the price of secondhand housing had a downward trend. Overall, the Xiong'an New Area policy had a significant influence on the quantity of new and secondhand housing and the prices of the new and secondhand housing index in Beijing. Based on the empirical results, to promote the rational development of Beijing's real estate market through the Xiong'an New Area policy, and to achieve the national policy goal of "no speculation on housing"and "housing for housing the planning and construction in the area need to be strengthened. © 2022 American Society of Civil Engineers.

摘要:
随着农地流转的深化,土地规模化经营能否促进农村产业融合发展亟待研究。本文基于中国省级面板数据,通过测算农村产业融合发展水平,利用双向固定效应模型和系统广义矩估计方法,实证检验土地规模化经营对农村产业融合发展的影响及其传导机制。进一步基于2020年CLES农户调查数据,利用Logit模型探究了土地规模化经营影响农户参与农村产业融合发展行为的微观基础。研究表明:(1)从宏观层面来看,土地规模化经营对农村产业融合发展具有推动作用,影响机制分析表明其受到农村劳动力转移和农村居民收入水平的正向调节作用,且是通过提升农村居民收入水平来推动农村产业融合发展。(2)从微观层面来看,土地规模化经营推动了农户参与农村产业融合发展行为,且是通过提高农户参与农业技术培训积极性来推动农户家庭参与农村产业融合发展行为。因此,推动土地规模化经营与实现农村产业融合发展在政策目标上具有协同性,为实现农村产业融合发展,政府应实施有利于土地规模化经营的配套制度,拓宽农村居民收入渠道,有序推进农村劳动力转移,完善农业技术培训服务,助力农村产业融合发展。

摘要:
As loss in decision sample information occurs during large-scale group decision-making (LSGDM), this paper proposes a statistical estimation approach for handling Pythagorean fuzzy information under the risk attitude of decision-makers (DMs). The DMs are partitioned by risk attitudes (hesitancy degrees) into subgroups. A five-number summary for the subgroups from the incomplete decision information given by the DMs is obtained. The Cornish-Fisher expansion is then applied to estimate the mean, standard variance, and skewness of the decision sample information from the five-number summary. The confidence interval constructed by the skewness is used to obtain the interval-valued Pythagorean fuzzy number (IVPFN) evaluation information of the subgroups. An optimization model based on minimizing the conflicts between the subgroups and the overall group is used to derive the weights of the subgroups. A sorting function of the IVPFNs is used to rank the alternatives. A case study on green credit and a comparison analysis are applied to validate the proposed method. (C) 2021 Elsevier B.V.

摘要:
In the current research, we developed and tested a model of how and when social comparison of received help influenced the recipient’s job performance (i.e., interpersonal citizenship behavior, task performance). Based on social exchange theory and social comparison theory, we posited that social comparison of received help influenced the recipient’s feelings of gratitude, which in turn had a positive relationship with interpersonal citizenship behavior (ICB) and task performance. Further, we argued that the recipient’s psychological entitlement influenced the effects of social comparison of received help. Using data collected in three waves from 307 employees in China, we found that social comparison of received help was positively associated with the recipient’s feelings of gratitude while controlling for overall received help. Gratitude, in turn, benefited ICB and task performance. Moreover, high levels of psychological entitlement weakened the relationship between the social comparison of received help and the recipient’s feelings of gratitude. Further, they weakened the indirect relationship between the social comparison of received help and the recipient’s ICB and task performance via gratitude. These findings could potentially extend our knowledge of received help literature by introducing a social comparison perspective. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

摘要:
How environmental regulation affects factor allocation is becoming an emerging hot topic in academia. In this paper, we construct a dynamic general equilibrium model accommodating environmental regulatory shock based on the H-K framework to explain the impact of environmental regulation on factor misallocation from the perspective of aggregate total factor productivity loss changes, and numerical simulation results are provided for several representative scenarios. The results show that environmental regulation has a significant effect on factor market misallocation, but this effect is not simply positive or negative, and it mainly depends on the firms’ initial factor allocation status and the intensity of the shock. Reducing the intensity of environmental regulation for firms that face stronger distortion helps mitigate factor misallocation and, on the contrary, the same policy could exacerbate factor market misallocation. Under the environmental regulatory shock condition, firms’ overhead labor input has a moderating effect on the factor allocation mitigation of environmental regulation. Distorted firms’ higher overhead labor share inhibits the correction of factor misallocation by environmental regulation. And reducing firms’ overhead labor share amplifies the correcting effect of environmental regulation on factor misallocation. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.
