This paper is a historical survey of western construction of the images of Con-fucianism ranging from the sixteenth century to nineteenth century. The historical process ofWestern version of Confucianism originally was traced back to European missionaries, whoplayed crucial role in collecting Confucian primary sources and praising the ethical and socialvalues of Confucianism. Inspired by the primary sources of Confucianism, Enlightenmentscholars represented the image of Confucianism as romanticized ideal of natural theory andpractical morality for European culture. However, western＇ s imagination of Confucianism inthe nineteenth century shifted from a cultural and political ideal to childish and static traditioninferior to European culture, as emphasized in Hegel and Herder＇ s works. All these Westernimages of Confucianism illustrate the historical expressions of European self - presentation,self- confirmation and self- criticism.

This paper develops a simple trade model of heterogeneous firms, which incorporates the dual heterogeneity of credit constraints at the firm and industry levels and reveals the effects of the interaction mechanisms of trade policy uncertainty and credit constraint heterogeneity on exporters’ behaviour. The model confirms that the higher the level of industrial credit constraints, the greater the interaction of trade policy uncertainty and credit constraint heterogeneity, but firms with lower levels of credit constraints within a specific industry are more affected by this interaction. Then, based on the highly dis-aggregated trade data of China’s firms from 2000 to 2013, this paper provides empirical evidence for the main predictions and mechanisms of the theoretical model.

The shale gas exploration of marine-continental transitional facies has gained great attention in China， which is viewed as another breakthrough following the marine shale gas prior to continental shale gas. The Upper Paleozoic marine-continental transitional shales have high TOC abundance with large total thickness in the eastern Ordos Basin， progressively becoming a favorable area for exploration of transitional shale gas. Nevertheless， compared with the relatively homogeneous marine shales， the marine-continental transitional shales demonstrated strong anisotropy in the aspects of thickness， lithology and organic matter (OM). Thus， in this paper， based on the trace element and rock-eval data， we investigated the sedimentary facies， provenance， paleoclimate， paleobathymetry， and redox condition， as well as their controls on the enrichment of organic matter in the Shenfu Block， eastern Ordos basin. The results of trace element experiments indicate that the paleoenvironment of the Ordos Basin underwent a transition from a marine to a continental environment， evolving from the Benxi Formation of the Carboniferous system to the Upper Shihezi Formation of the Permian system. The provenance area is characterised by the presence of high iron and high magnesium feldspar， with a medium degree of weathering. The paleoclimate experienced alternating periods of dry heat， relatively warm wet conditions， and dry heat. The paleowater depth decreased along the sedimentary profile. With regard to the REDOX environment index， the Taiyuan Formation is the stratum exhibiting the highest degree of reduction. The detection criteria for biomarkers were found to be consistent with the inorganic geochemical characteristics. The relationship between various trace elements and TOC indicates that redox conditions are the primary factors influencing the accumulation of organic matter in transitional shale. Organic matter is more abundant in warm and humid marine and terrestrial environments t

Hydrogenating CO2is acknowledged as a structure-sensitive reaction, where structural changes of catalysts profoundly influence the product distribution and catalysts activity. However, traditional characterization techniques（so-called ex situ） fail to accurate and authentic detection of the structure of catalysts and reaction pathway changes when the catalyst is in the working state. To address this issue, in situ/operando spectroscopies have been developed to elucidate the structure-activity relationships of catalysts in the thermo-catalytic CO2hydrogenation process, advancing our understanding and guiding the design of catalysts. In particular, Raman spectroscopy and X-ray absorption spectroscopy（XAS） can be used to monitor the real-time changes of catalyst structures, elucidating the metal（or oxide）-support interaction, identifying active sites and investigating the causes of catalyst deactivation. Fourier-transform infrared spectroscopy（FTIR） can be employed to track the evolution of surface intermediates during the reaction, inferring plausible reaction mechanisms. Combined with steady-state isotope transient kinetic analysis（SSITKA） experiments, it provides valuable insights into the kinetics information of surface species. In this review, we summarize the up-to-date advances in these spectroscopic techniques and delineate potential future trends in the CO2reduction.
