Additive trapezoidal fuzzy preference relation;Priority vector;Compatibility;COWA operator;Optimization model
摘要:
Considering the conflicting opinions and different risk attitudes among decision-makers (DMs) in group decision making (GDM), this paper develops a novel compatibility model with additive trapezoidal fuzzy environment based on continuous ordered weighted averaging (COWA) operator to handle the conflicts. First, some concepts of COWA operator-based compatibility index and characteristic preference relation for additive trapezoidal fuzzy preference relation (ATFPR) are discussed. Then a compatibility reaching algorithm is designed to assist each ATFPR in achieving acceptable compatibility. Moreover, the expert weight optimization model based on the criterion of minimum compatibility of preference relation in GDM is established. Furthermore, a GDM process based on compatibility measures with ATFPRs is introduced, and an application of the proposed approach is put forward. The novelties of our approach are that: (1) COWA operator can deal with the compatibility of all arguments by using controlled parameters that consider the risk attitudes of DMs rather than the compatibility of the simply two points in intervals; (2) compatibility improving algorithm makes sure that the original opinions are retained as much as possible because only one pair of preference relation elements are revised in each round; (3) optimal weights model ensures that weights of DMs in group aggregation are determined availably.

摘要:
Abstract: Medium-term hydrological streamflow forecasting can guide water dispatching departments to arrange the discharge and output plan of hydropower stations in advance, which is of great significance for improving the utilization of hydropower energy and has been a research hotspot in the field of hydrology. However, the distribution of water resources is uneven in time and space. It is important to predict streamflow in advance for the rational use of water resources. In this study, a Bayesian model average integrated prediction method is proposed, which combines artificial intelligence algorithms, including long-and short-term memory neural network (LSTM), gate recurrent unit neural network (GRU), recurrent neural network (RNN), back propagation (BP) neural network, multiple linear regression (MLR), random forest regression (RFR), AdaBoost regression (ABR) and support vector regression (SVR). In particular, the simulated annealing (SA) algorithm is used to optimize the hyperparameters of the model. The practical application of the proposed model in the ten-day scale inflow prediction of the Three Gorges Reservoir shows that the proposed model has good prediction performance; the Nash–Sutcliffe efficiency NSE is 0.876, and the correlation coefficient r is 0.936, which proves the accuracy of the model.

Portfolio allocation;Complete EEMD with adaptive noise;Financial data denoising;CEEMDAN denoising
摘要:
Effective denoising strategies are increasingly important for portfolio investors. Considering that the common ensemble empirical mode decomposition (EEMD)-based stepwise denoising algorithms suffer from white noise interference and ignore the effect of low-frequency redundant noise components on the portfolio, a novel complete EEMD with adaptive noise (CEEMDAN) denoising algorithm is proposed to improve the portfolio performance. Specifically, we apply CEEMDAN to decompose noisy prices into a series of intrinsic mode functions (IMFs). Then, a series of tests based on the correlations between the original noisy prices and the decomposed IMFs are performed to identify which IMFs are noisy modes. If the tests accept the null hypothesis, the IMFs are considered as noisy components. Finally, we use the soft-threshold technique to process the noisy components and sum the non-noisy components to construct the denoised prices. The empirical results show that under the dynamic minimum-CVaR framework, the proposed CEEMDAN denoising algorithm is not affected by white noise and outperforms the EEMD denoising and stepwise denoising algorithms in improving out-of-sample portfolio returns. Overall, the proposed CEEMDAN denoising is the optimal denoising algorithm, which can help investors improve portfolio performance to the greatest extent.

Grey system theory;Multiobjective grey wolf optimizer;Time series prediction;Weakened accumulation operator
摘要:
As a combination of the differential equation prediction model and intelligent optimiza-tion algorithm, the grey intelligent prediction algorithm has attracted increasing attention due to its outstanding performance in small-sample environments. However, most studies focus only on the improvement of algorithm performance, with little regard to the uni-formity, ill-condition and overfitting of the algorithm. To promote the development of this field, we develop a new grey intelligent prediction algorithm with multiobjective correc-tion strategy based on the new weakened accumulation grey optimization model and the multiobjective grey wolf optimizer. In this new prediction algorithm, the new weakened accumulation operation is utilized to enhance the predictive ability of the algorithm and mitigate the ill-condition of the system, the Bernoulli parameter and a discretization tech-nique are used to activate the uniformity and unbiasedness of the algorithm, respectively, and the multiobjective grey wolf optimizer is employed to alleviate the overfitting of the system. Compared with the previous grey intelligent prediction models, the new prediction algorithm is more perfect and reasonable. Taking two energy datasets as research cases, the evaluation results of a system consisting of six evaluation metrics and the Diebold -Mariano test show that the proposed model outperforms the other six comparative mod-els in terms of prediction performance and stability, which confirms the feasibility and validity of the algorithm.

Grey system model;Fractional -order accumulation;Grey neural network;Predictive model
摘要:
Recently, grey system, neural network, and fractional order calculus theory have become popular research areas, and an increasing number of scholars have joined these studies, conducted illuminating research, and produced a number of significant results. Numerous research studies have demonstrated that these three strategies are crucial to solving a wide range of practical problems. In this paper, we present a fractional order neural grey system model with a three-layer structure in which the input of the network is a fractional order cumulative sequence, and the output is a predicted value in order to maximize the bene-fits of each of the three elements. The purpose of this research is to present a strategy for reducing the number of conditions in order to improve the stability of parameter estima-tion by using QR decomposition. The order of the models is determined by an intelligent optimization algorithm. Finally, real-world examples are used to validate the model's va-lidity, and experimental results indicate that the newly presented model is more accurate than previous models. (c) 2023 Elsevier Inc.

摘要:
The impact of the digital economy (DE) has become the important faction of the market volume of domestic non-tradable sectors (DNSs). As rising digitalization supersedes traditional market power as a driving force, there is increasing concern about the volume of trade and economy; however, the literature of how the DE procession changed the DNS's are limited, although the Chinese government is eager to enlarge the scale of the domestic market to be consistent with the trend of digitalization. This paper addressed this issue by employing a series of data from prefecture-level cities between 2010 and 2019 in China. Using panel data methods under fixed effect, synthetic difference-in-differences (SDID), and temporal-spatial econometrics, the paper's hypothesis sheds light on the positive impact of the DE on DNSs. The regression results showed a 14.84% of improvement for the effects of DE development on DNS growth. The policy impact effect increased the average treatment effect by 3.9% average treatment effect, accompanied by temporal and spatial correlations. Further analysis illustrated that a possible intermediary mechanism through which the DE promotes the development of DNSs is the enhancement of the local product market development. It was concluded that policy-makers of developing countries should be devoted to breaking down domestic trade barriers among different regions to enhance the benefits of digitalization.

摘要:
Abstract: Drawing on the existing research on green leadership, this paper first examines the concept and structure of executive green leadership and develops a preliminary scale to measure executive green leadership. The confirmatory factor analysis is adopted to verify and revise the scale. The results show that green leadership and green person are the two main structures of executive green leadership, and the scale developed in this paper is of good reliability and validity. After data analysis, this paper then explores the antecedents of executive green leadership. The results show that factors such as corporate executives’ internal moral identity, conscientiousness, pro-environmental intention, command-based environmental regulation, market-based environmental regulation, and corporate green image have a significant positive correlation with executive green leadership, while their short-term orientation has a significant negative correlation with the green leadership. This paper defines the concept and structure of executive green leadership and develops the corresponding scale for measuring it, to improve scholars’ and managers’ understanding of executive green leadership.

Salmon price risk hedging;fuzzy copula model;Kullback-Leibler divergence;mixture Gaussian model
摘要:
Copula method can explain the dependent function or connection function which connects the joint distribution and the univariate marginal distribution. Therefore, copula has recently become a most significant important tool in the financial field of risk management, portfolio allocation, and derivative asset pricing. However, it leads to a possibilistic uncertainty in estimating the parameters of copulas because of insufficient historical data, imprecise parameter estimation, and uncertain knowledge of future prices. This paper proposes a fuzzy copula model via Kullback-Leibler (KL) divergence to model the fuzzy relations, and further to investigate the hedging issues of salmon futures. We use a new framework of hedging under fuzzy circumstances, consisting of innovative marginal distributions and fuzzy intervals. By synergizing fuzzy copula and simulations, we use the fuzzy copula-GMM to obtain the hedge ratios of salmon futures. The empirical results show that, compared with traditional probabilistic methods, the fuzzy copula-GMM hedges the salmon spot risk measured by variance more successfully.
摘要:
Abstract: In the context of building a “Beautiful China”, it is imperative to strengthen environmental regulations to restrict industrial pollution emissions. However, there are significant differences of regulations intensity among different regions, which will lead to an increase in the cost of compliance with regulations for polluting industries, so these industries tend to transfer from areas with strong environmental regulations to areas with weak environmental regulations. Based on the panel data of 282 prefecture-level cities and national patent data from 1994 to 2010, this paper constructs a difference in difference model (DID) to empirically study the impact of environmental regulations on regional industrial transfer and its mechanism. We find that, firstly, the “Two-Control Zones” policy has significantly promoted regional industrial transfer, and its effect has gradually increased in the long run. Then, the promotion effect of the “Two-Control Zones” policy on regional industrial transfer is heterogeneous among different regions due to the regional market environment and resource endowment; that is, the promotion effect is the greatest in Central China, then in Eastern China, and finally in Western China. At the same time, the frequency of industrial transfer in areas with high resource dependence is significantly lower than that in areas with low resource dependence. Finally, mechanism studies find that environmental regulation enhances inter-regional industrial liquidity and promotes regional technological innovation, and the role of environmental regulation on technological innovation is more obvious in regions with weak industrial liquidity. This proves that the “Pollution Heaven Hypothesis” and the “Porter Hypothesis” can be established at the same time in the Chinese context, which provides more reliable empirical evidence for the government to formulate environmental regulations, restrict pollution emissions, and balance environmental governance and sustainable economic development.

摘要:
In recent years, the Chinese Central Government has put great emphasis on the marine economy, since it has been a new driving force of the national economic development. Yet, the relationship between marine economic development and energy efficiency remains unknown. In this paper, we investigate whether marine economic development affected energy efficiency. We focused on the Zhoushan Archipelago, the first National New Area for marine economic development in China. We applied panel data approach to construct the counterfactual of Zhoushan Archipelago. We compared Zhoushan and its counterfactual, the synthetic Zhoushan, and viewed the difference between them, after the Zhoushan Archipelago New Area, as the impact of marine economic development on energy efficiency. We found that compared with its counterfactual, the real Zhoushan had a more substantial improvement in energy efficiency after the National New Area construction. We estimated that the construction of the National New Area for Marine Economy increased energy efficiency by about 10 percentage points. We also applied the bootstrapping technique to illustrate the significance of the estimated results. The results suggest that the Zhoushan Archipelago New Area construction had a statistically significant impact on energy efficiency. In addition, we conducted two tests, including leave-one-out tests and permutation tests, to check the robustness of estimated results, which also serve as an illustration of significance of the estimated results from an alternative empirical perspective. The results from these two tests are similar to each other, both indicating that the Zhoushan Archipelago New Area construction had a statistically significant positive impact on energy efficiency. Overall, our results suggest that marine economic development had a sizable improvement in energy efficiency.

摘要:
The global spread of COVID-19 has led to profound reflection on building a global public health security system. This paper uses the urban data collected during the COVID-19 epidemic in China in 2020 to evaluate the effect of the National Sanitary City (NSC) policy on the prevention and control of that epidemic at different stages. We found that the NSC policy was able to curb the occurrence and transmission of the epidemic the epidemic effectively after controlling a series of factors such as urban characteristics, population mobility and pathogen transmission. Compared with non-NSCs, the NSCs were better able to control the number of infected people and the infection rate and transmission rate, and this performance was even more impressive when the epidemic gradually entered the sporadic distribution stage. The heterogeneity analysis shows that the impact of the NSC policy on the prevention and control of COVID-19 differs according to the economic development level and population size. To a certain extent, the NSC policy has blocked the spread of viruses by continuously improving the urban medical and health system and strengthening the publicity concerning infectious disease prevention and control knowledge.

摘要:
INTRODUCTION: Adolescence is a sensitive transitional period accompanied by great physical, mental, and behavioral changes. Therefore, maintaining physical and mental health is crucial to the growth and development of adolescents. As one of the important indicators of mental health, the influencing factors of life satisfaction have been widely concerned by scholars. In recent years, with the rapid development of Internet technology, mobile social media has penetrated into all aspects of adolescents' life, which has a subtle impact on their physical and mental health. Existing studies have indicated that mobile social media use can affect adolescents' life satisfaction. However, little is known about the mediating and moderating mechanisms linking this association. This study developed a moderated mediation model to examine the mediating role of meaning in life and the moderating role of childhood psychological maltreatment. METHODS: A total of 1,198 adolescents across four provinces and municipalities of China completed questionnaires on mobile social media use, life satisfaction, meaning in life, and childhood psychological maltreatment. RESULTS: After controlling for gender and age, the results demonstrated that mobile social media use was positively associated with life satisfaction and meaning in life among adolescents. Moreover, meaning in life fully mediated the association between mobile social media use and life satisfaction. Finally, the association between mobile social media use and life satisfaction, as well as that between mobile social media use and meaning in life, was moderated by childhood psychological maltreatment. Specifically, these associations are stronger for adolescents with high levels of psychological maltreatment. DISCUSSION: These findings shed light on the important mechanism underlying mobile social media use's effects on adolescents' life satisfaction, which is helpful to formulate targeted measures for improving adolescents' life satisfaction.

摘要:
Property enterprise has contributed significantly to the prevention and control of COVID-19, and its functions received positive feedback from the urban residents via a survey. Detailed data on confirmed COVID-19 cases in 446 communities in Wuhan were collected and the property fee of each community was used to assess the quality of the property services provided. Both binary logit and ordered logit models were used to measure the impact of property fees on the pandemic prevention and control efficiency of each community. The results showed that a higher property fee corresponded to a better property service and a higher probability that the residential community would be free of COVID-19. Furthermore, where property fees were higher, pandemic prevention and control efficiency increased and the community achieved a lower pandemic risk level. In conclusion, the promotion of high-quality property services is conducive to community disease prevention and control in the case of a pandemic.

Large-scale group decision-making;Statistics;Reliability;Interval linguistic distribution preference;relation;Entropy measure
摘要:
Aiming at large-scale decision-makers (DMs) and the loss of decision sample information in large-scale group decision-making (LSGDM), a novel statistical estimation method incorporating the reliability and entropy of linguistic distribution assessment is proposed. First, classify the large-scale DMs into several subgroups according to their prior decision efficiency distribution. After clustering, collect the five-number summary of the incomplete decision sample information provided by the DMs in the subgroups. Second, estimate the mean, standard deviation, skewness and kurtosis of the decision sample via the Cornish-Fisher expansion. Then utilize the Bayes estimation to address the reliability of the subgroups, thereby obtaining the confidence interval, which is used to develop the interval linguistic distribution preference relation (ILDPR) for the subgroups. Moreover, combine the reliability and the entropy measure constructed by the above four estimators to determine subgroup weights. Furthermore, present the expectation and variance of the ILDPR to sort the alternatives. Finally, demonstrate the feasibility and validity of the proposed LSGDM method based on a case and a comparison.
