摘要：
Innovation, as a driving force to economic growth, has been referred to as an important development strategy by the central government of China. In order to improve the innovative capability of cities, Chinese officials started to construct innovation cities in 2008. Previous studies have investigated the ecological and economic effects of innovation city construction; however, the environmental effect of the project remains unclear. In this study, we constructed an annual panel of 285 cities in China, from 2007 to 2015, to assess the effect of innovation city construction on carbon emissions. Our baseline results are obtained from a difference-in-differences estimator, comparing cities with and without introducing innovation city construction, whose results show that innovation city construction reduces carbon emissions by about 2% on average. We found a similar effect of innovation city construction on carbon emissions when we controlled for the estimated propensity of a city to launch the innovation city construction based on a series of urban characteristics, such as gross regional product and population. We obtained comparable estimates when we used the propensity score as weights to balance urban characteristics between cities with and without launching the innovation city construction. Our results also show that innovation city construction has a larger effect on carbon emissions in western, poorer, and fewer population cities than in those with opposite characteristics. We found suggested the persistence of the effect that innovation city construction had on carbon emissions, implying that the Chinese government should encourage innovation to reduce carbon emissions. Besides, we performed a series of robustness tests, including the leave-one-city-out test, the bootstrapping test, and the permutation test, to illustrate the robustness of our results.

摘要：
PurposeThis study aims to test the possible correlation between the letter height-to-width ratio and consumers' perception of cuteness. Design/methodology/approachThrough the design of three groups of experimental questionnaires, this paper carried out experiments on subjects with different professional backgrounds. FindingsThe result shows that perceived cuteness is only beneficial for consumers who adopt communal relationship (rather than exchange relationship) with the brand. Compared to consumers who adopt communal relationship with brands, letters of lower height-to-width ratio are perceived as cuter and thus more preferable than thinner ones, whereas for consumers who adopt exchange relationship with brands, thinner letters are preferred. Research limitations/implicationsTo rule out interference, this study focuses only on the height-to-width ratio of the letters. In the future, researchers can pay more attention to the mobility of brand relationships, consumers' reading strategy and logos' visual elements that influence consumers' brand perception (besides height-to-width ratio). Practical implicationsThe research reminds scholars that the height-to-width ratio of letters/logos is not only of aesthetic value but also imposes a great impact on consumer perception. And the result of this research explains the contradiction in consumers' preference for wide vs thin letter shapes and provides evidence for the interaction between brand relationship norms and letter preferences. Originality/valueTo the best of the authors' knowledge, this research is the first to explore the influence of letter height-to-width ratio in marketing.

摘要：
Consensus reaching process is a useful decision tool to reduce the preference conflict among experts in multi-criteria group decision-making (MCGDM). Often, the consensus is reached by the experts adjusting their assessments to the extent of mutual agreement. Accordingly, the purpose of this article is to develop an improved consensus-based method with interval fuzzy number judgment matrix (IFJM). To determine the disputes between experts, the consensus measure of IFJM based on objective and subjective compatibility degrees is defined. According to the consensus measure, a consensus improving algorithm is presented to assist each IFJM in reaching acceptable consensus. Subsequently, an optimization model based on the criterion of minimizing the consensus measure of IFJM with acceptable consensus is established to determine weights of experts in MCGDM. To rank and select alternatives, the possibility degree matrix is used to obtain the priority vector. Thus, a new consensus-based approach is put forward to solve MCGDM with IFJM. In this context, a case of express packaging recycling in circular economy and some comparisons are analyzed to demonstrate the availability and effectiveness of the proposed method.

摘要：
This paper studies large sample properties of a moderately explosive autoregression with a structural change in the unobservable drift term, and develops asymptotic tests for the null of moderate explosiveness under different dependence structures. When the innovation sequence is independently and identically distributed (i.i.d.), we show that the t statistic is asymptotically standard normal. When the innovations are weakly dependent in the form of homoskedasticity or conditional heteroskedasticity, we invoke the fixed-smoothing asymptotics to construct the heteroskedasticity and autocorrelation robust standard error, under which the t statistic follows Student's t distribution in large samples. Monte Carlo simulations show that our tests have small size distortion and high power in finite samples. As we impose no restrictions on the occurrence time and magnitude of the drift, our proposed asymptotic tests enjoy strong robustness and applicability.

Model -driven hedging strategy;PSO-HMM;State -dependent hedging strategy;State identi fi cation
摘要：
Relying on the hidden Markov model improved by the particle swarm optimization algorithm (PSO-HMM), we develop a dual-decision method to address the issue of state-dependent futures hedging. Our approach is attractive in two ways. First, it uses the PSO algorithm to overcome the shortcomings of the traditional algorithm, which can easily fall into the local optima to estimate parameters in a hidden Markov mode. Second, this paper proposes a new hedge position adjustment method based on the identified market states, instead of sticking to the hedge position calculated by the commonly used GARCH-type models to achieve a better trade-off between risk hedging and return acquisition. Specifically, we first improve the accuracy of parameter measurement and employ the PSO-HMM to identify two market states, bear and bull, and fully illustrate the rationality and effectiveness of the proposed model. Based on the market states identified, we then adjust the hedge ratio estimated by GARCH-type models and compare the hedging effects of no hedge, model-driven, and state-dependent strategies. Our empirical results show that the PSO-HMM method can improve the accuracy of state identification over the classical HMM. The market state-dependent hedging strategy has better performance than other strategies when it comes to the trade-off between the return and the risk of a hedged portfolio. Furthermore, robustness checks under different conditions confirm that the state-dependent hedging strategy outperforms the model-driven hedging and no hedge strategies. Thus, our research sheds new light on conventional hedging models. Copyright (c) 2022 Borsa Istanbul Anonim S,irketi. Published by Elsevier B.V.
