China is facing challenges to sustainable economic growth. Higher education of Chinese residents can affect total factor productivity (TFP) growth and hence has an influence on economic sustainability. However, currently, there is limited literature on the nexus between higher education and TFP in China. Therefore, this paper empirically analyzes the heterogeneous and spatial effect of higher education on the regional TFP growth using a dynamic spatial econometric model with provincial panel data from 2003 to 2016. The results indicate that different levels of higher education have significant effects on TFP growth and are mainly reflected in the spatial spillover effect. Bachelor and doctoral education (particularly doctoral education) demonstrated significant positive effects, whereas the technical school and master education had significant negative effects. When decomposing this effect into technical efficiency and technical progress to explore the mechanism of influences, the latter plays the major role. Therefore, the Chinese government can promote TFP growth and economic sustainability by expanding the scale of bachelor and doctoral education and improving the quality of technical and master education.

As a human rights researcher with national affections, the author of Human Rights: China's Road tries to understand the underlying logic of human rights situations in China and the progress happening there.The author believes that the idea of human rights protection is unconditionally agreed upon by everyone, but the choice of specific patterns and routes is neither justified nor possible to remain unchanged through all the different concrete scenarios. For the 1.4 billion Chinese people, only they themselves are entitled to determine how they should protect their own human rights, and how to

This Ph. D. work is motivated by the possibility of monitoring the conditions of components of energy systems for their extended and safe use, under proper practice of operation and adequate policies of maintenance. The aim is to develop a Support Vector Regression (SVR)-based framework for predicting time series data under stationary/nonstationary environmental and operational conditions. Single SVR and SVR-based ensemble approaches are developed to tackle the prediction problem based on both small and large datasets. Strategies are proposed for adaptively updating the single SVR and SVR-based ensemble models in the existence of pattern drifts. Comparisons with other online learning approaches for kernel-based modelling are provided with reference to time series data from a critical component in Nuclear Power Plants (NPPs) provided by Electricité de France (EDF). The results show that the proposed approaches achieve comparable prediction results, considering the Mean Squared Error (MSE) and Mean Relative Error (MRE), in much less computation time. Furthermore, by analyzing the geometrical meaning of the Feature Vector Selection (FVS) method proposed in the literature, a novel geometrically interpretable kernel method, named Reduced Rank Kernel Ridge Regression-II (RRKRR-II), is proposed to describe the linear relations between a predicted value and the predicted values of the Feature Vectors (FVs) selected by FVS. Comparisons with several kernel methods on a number of public datasets prove the good prediction accuracy and the easy-of-tuning of the hyperparameters of RRKRR-II. ; Ce travail de thèse est motivée par la possibilité de surveiller l'état des composants de systèmes d'énergie pour leur utilisation prolongée et sécuritaire, conformément à la pratique correcte de fonctionnement et des politiques adéquates de maintenance.

La motivation est de développer des méthodes basées sur la régression à vecteurs de support pour la prédiction de données de séries chronologiques dans des conditions environnementales et opérationnelles stationnaire/ non-stationnaire. Les simples modèles et les ensembles de modèles à base de SVR sont développés pour attaquer la prédiction basée sur des petits et des grands ensembles de données. Des stratégies sont proposées pour la mise à jour de façon adaptative les simples modèles et les ensembles de modèles à base de SVR au cas du changement de la distribution générant les données. Les comparaisons avec d'autres méthodes d'apprentissage en ligne sont fournies en référence à des données de séries chronologiques d'un composant critique dans les centrales nucléaires fournis par Electricité de France (EDF). Les résultats montrent que les approches proposées permettent d'atteindre des résultats de prédiction comparables compte tenu de l'erreur quadratique moyenne et erreur relative, en beaucoup moins de temps de calcul. Par ailleurs, en analysant le sens géométrique de la méthode de la sélection de vecteurs caractéristiques(FVS) proposé dans la littérature, une nouvelle méthode géométriquement interprétable, nommé Reduced RankKernel Ridge Regression-II (RRKRR-II), est proposée pour décrire les relations linéaires entre un valeur prédite et les valeurs prédites des vecteurs caractéristiques sélectionné par FVS. Les comparaisons avec plusieurs méthodes sur un certain nombre de données publics prouvent la bonne précision de la prédiction et le réglage facile des hyperparamètres de RRKRR-II.

The Chinese government adopted more specific and stringent environmental impact assessment (EIA) guidelines in 2011, soon after the widespread ethnic protests against coal mining in Inner Mongolia. However, our research suggests that the root of the ethnic tension is a sustainability problem, in addition to environmental issues. In particular, the Mongolians do not feel they have benefited from the mining of their resources. Existing environmental assessment tools are inadequate to address sustainability, which is concerned with environmental protection, social justice and economic equity. Thus, it is necessary to develop a sustainability impact assessment (SIA) to fill in the gap. SIA would be in theory and practice a better tool than EIA for assessing sustainability impact. However, China's political system presents a major challenge to promoting social and economic equity. Another practical challenge for SIA is corruption which has been also responsible for the failing of EIA in assessing environmental impacts of coal mining in Inner Mongolia. Under the current political system, China should adopt the SIA while continuing its fight against corruption.

Industry-university-research cooperation is an important mission of higher education. It can meet the demands of multiple subjects, such as universities, scientific research institutes, and enterprises, and help integrate educational resources; thus, it is an important way to train technological innovation talent in application-oriented universities. Given the background of industry-university research, this paper analyzes the problems faced by application-oriented universities in the training of innovative talent in application-oriented universities, including the lagging concept of collaborative education, the immature collaborative education model and mechanism, the mismatch between the major setting and industry of collaborative education, and cooperation in collaborative education. We elaborated the development of innovative talent in application-oriented universities from the perspective of industry-university research from four aspects: improving the enthusiasm of the subject of collaborative education, deepening the supply-side reform of talent training, cobuilding an innovation platform for the integration of industry-university research, and building an information service platform for collaborative education. We propose three empowering countermeasures, namely, the creation of a good institutional environment, the establishment of a leading group for collaborative education, and the establishment of a joint industry-university-research fund, to provide beneficial suggestions for the training of high-quality innovative talent in application-oriented universities in China.

AbstractIn the online retailing, consumers are commonly uncertain about the product's quality and fitness. To resolve these uncertainties, many pure e‐tailers adopt various omnichannel strategies to provide tactile product information for consumers. We build a model to investigate a pure e‐tailer's decision on whether to adopt an omnichannel strategy. Our result indicates that when the cost for each physical store is sufficiently low, the e‐tailer always adopts the omnichannel strategy regardless of the product quality. Moreover, the low‐quality e‐tailer's willingness to adopt the omnichannel strategy is nonmonotonic with the fitness probability when the travel cost factor is high. In contrast, if the cost for each physical store is moderate, the e‐tailer adopts the omnichannel strategy if and only if the product quality is above a threshold. The quality threshold may increase with the fitness probability. Higher fitness probability means a lower return rate and fewer benefits brought by the omnichannel strategy. Thus, the threshold of the quality is increased to guarantee a sufficiently large price increase when choosing the omnichannel strategy. Furthermore, when the cost for each physical store is high, the e‐tailer with a high‐quality product would abandon the omnichannel strategy if the fitness probability is moderate. Finally, we consider the scenarios in which the e‐tailer can endogenously determine the number of physical stores or provide a partial refund policy.
