We apply this framework to the global Concentrated Solar Power sector, in which China has rapidly narrowed the gap to the global forefront in terms of technological capabilities and market competitiveness. We find that the formative nature of the sector resulted in turbulent development of the technological, market, and institutional dimensions, making it more difficult for early leaders to retain leadership, and therefore easier for latecomer firms or countries to catch up.

We find that the Chinese CSP sector has good potential for becoming internationally competitive because of a strong Chinese knowledge base, a clear eye for product quality, standard-setting, and a focus on the high-efficiency and large-storage technological routes most likely to see growing demand in future international markets. Chinese solar towers are already cheaper than international competitors and so far, appear reliable. However, continued and stable deployment support for CSP, designed to reward dispatchable solar power generation, enabling continued domestic learning-by-doing and -interacting is likely required to realize this export potential. To date, Chinese CSP policy has done many things right and, if the domestic market is maintained through renewed support, has put the Chinese industry well on the path to international competitiveness.}, language = {en} } @incollection{Rieck2023, author = {Rieck, Christian E.}, title = {Region ohne Richtung}, series = {Zwischen Moskau, Peking und Washington: Lateinamerika in der Großmachtkonkurrenz}, booktitle = {Zwischen Moskau, Peking und Washington: Lateinamerika in der Großmachtkonkurrenz}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {978-3-7560-0033-3}, doi = {10.5771/9783748936121}, pages = {121 -- 130}, year = {2023}, abstract = {Welche Auswirkungen wird die aufziehende Großm{\"a}chtekonkurrenz also auf die regionale Sicherheitsordnung haben?

Expected and observed effects of digitalisation in industry for environmental sustainability}, doi = {10.25932/publishup-61395}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-613954}, school = {Universit{\"a}t Potsdam}, pages = {vii, 168}, year = {2023}, abstract = {Digitalisation in industry - also called "Industry 4.0" - is seen by numerous actors as an opportunity to reduce the environmental impact of the industrial sector. The scientific assessments of the effects of digitalisation in industry on environmental sustainability, however, are ambivalent. This cumulative dissertation uses three empirical studies to examine the expected and observed effects of digitalisation in industry on environmental sustainability. The aim of this dissertation is to identify opportunities and risks of digitalisation at different system levels and to derive options for action in politics and industry for a more sustainable design of digitalisation in industry. I use an interdisciplinary, socio-technical approach and look at selected countries of the Global South (Study 1) and the example of China (all studies). In the first study (section 2, joint work with Marcel Matthess), I use qualitative content analysis to examine digital and industrial policies from seven different countries in Africa and Asia for expectations regarding the impact of digitalisation on sustainability and compare these with the potentials of digitalisation for sustainability in the respective country contexts. The analysis reveals that the documents express a wide range of vague expectations that relate more to positive indirect impacts of information and communication technology (ICT) use, such as improved energy efficiency and resource management, and less to negative direct impacts of ICT, such as electricity consumption through ICT. In the second study (section 3, joint work with Marcel Matthess, Grischa Beier and Bing Xue), I conduct and analyse interviews with 18 industry representatives of the electronics industry from Europe, Japan and China on digitalisation measures in supply chains using qualitative content analysis. I find that while there are positive expectations regarding the effects of digital technologies on supply chain sustainability, their actual use and observable effects are still limited. Interview partners can only provide few examples from their own companies which show that sustainability goals have already been pursued through digitalisation of the supply chain or where sustainability effects, such as resource savings, have been demonstrably achieved. In the third study (section 4, joint work with Peter Neuh{\"a}usler, Melissa Dachrodt and Marcel Matthess), I conduct an econometric panel data analysis. I examine the relationship between the degree of Industry 4.0, energy consumption and energy intensity in ten manufacturing sectors in China between 2006 and 2019. The results suggest that overall, there is no significant relationship between the degree of Industry 4.0 and energy consumption or energy intensity in manufacturing sectors in China. However, differences can be found in subgroups of sectors. I find a negative correlation of Industry 4.0 and energy intensity in highly digitalised sectors, indicating an efficiency-enhancing effect of Industry 4.0 in these sectors. On the other hand, there is a positive correlation of Industry 4.0 and energy consumption for sectors with low energy consumption, which could be explained by the fact that digitalisation, such as the automation of previously mainly labour-intensive sectors, requires energy and also induces growth effects. In the discussion section (section 6) of this dissertation, I use the classification scheme of the three levels macro, meso and micro, as well as of direct and indirect environmental effects to classify the empirical observations into opportunities and risks, for example, with regard to the probability of rebound effects of digitalisation at the three levels. I link the investigated actor perspectives (policy makers, industry representatives), statistical data and additional literature across the system levels and consider political economy aspects to suggest fields of action for more sustainable (digitalised) industries. The dissertation thus makes two overarching contributions to the academic and societal discourse. First, my three empirical studies expand the limited state of research at the interface between digitalisation in industry and sustainability, especially by considering selected countries in the Global South and the example of China. Secondly, exploring the topic through data and methods from different disciplinary contexts and taking a socio-technical point of view, enables an analysis of (path) dependencies, uncertainties, and interactions in the socio-technical system across different system levels, which have often not been sufficiently considered in previous studies. The dissertation thus aims to create a scientifically and practically relevant knowledge basis for a value-guided, sustainability-oriented design of digitalisation in industry.}, language = {en} } @article{ZhangGuoChen2020, author = {Zhang, Yan-qiu and Guo, Zeng-hui and Chen, Dai-zhao}, title = {Porosity distribution in cyclic dolomites of the Lower Qiulitag Group (Upper Cambrian) in northwestern Tarim Basin, China}, series = {China geology}, volume = {3}, journal = {China geology}, number = {3}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2096-5192}, pages = {425 -- 444}, year = {2020}, abstract = {Increasing interests in hydrocarbon resources at depths have drawn greater attentions to the deeply-buried carbonate reservoirs in the Tarim Basin in China. In this study, the cyclic dolomite rocks of Upper Cambrian Lower Qiulitag Group from four outcrop sections in northwestern Tarim Basin were selected to investigate and evaluate the petrophysical properties in relation to depositional facies and cyclicity. The Lower Qiulitag Group includes ten lithofacies, which were deposited in intermediate to shallow subtidal, restricted shallow subtidal, intertidal, and supratidal environments on a carbonate ramp system. These lithofacies are vertically stacked into repeated shallowing-upward, meter-scale cycles which are further grouped into six third-order depositional sequences (Sq1 to Sq6). There are variable types of pore spaces in the Lower Qiulitag Group dolomite rocks, including interparticle, intraparticle, and fenestral pores of primary origin, inter crystal, and vuggy pores of late diagenetic modification. The porosity in the dolomites is generally facies-selective as that the microbially-originated thrombolites and stromatolites generally yield a relatively high porosity. In contrast, the high-energy ooidal grainstones generally have very low porosity. In this case, the microbialite-based peritidal cycles and peritidal cycle-dominated highstand (or regressive) successions have relatively high volumes of pore spaces, although highly fluctuating (or vertical inhomogeneous). Accordingly, the grainstone-based subtidal cycles and subtidal cycle-dominated transgressive successions generally yield extremely low porosity. This scenario indicates that porosity development and preservation in the thick dolomite successions are primarily controlled by depositional facies which were influenced by sea-level fluctuations of different orders and later diagenetic overprinting.}, language = {en} } @article{CarlaUhinkFreitag2022, author = {Carl{\`a}-Uhink, Filippo and Freitag, Florian}, title = {Theme Park Imitations}, series = {Cultural History}, volume = {11}, journal = {Cultural History}, number = {2}, publisher = {Edinburgh University Press}, address = {Edinburgh}, issn = {2045-290X}, doi = {10.3366/cult.2022.0267}, pages = {181 -- 198}, year = {2022}, abstract = {Theme parks frequently draw not only on historical themes, from antiquity to the roaring twenties, but also on their own history - that is, the history of the medium of the theme park itself.

We explore this assumption for the Holocene in eastern continental Asia (China, Mongolia). Boosted regression trees (BRT) between fossil pollen taxa percentages (Abies, Artemisia, Betula, Chenopodiaceae, Cyperaceae, Ephedra, Picea, Pinus, Poaceae and Quercus) and climate model outputs of mean annual precipitation (P-ann) and mean temperature of the warmest month (Mt(wa)) for 9 and 6 ka (ka = thousand years before present) were set up and results compared to those obtained from relating modern pollen to modern climate. Overall, our results reveal only slight temporal differences in the pollen climate relationships. Our analyses suggest that the importance of P-ann compared with Mt(wa) for taxa distribution is higher today than it was at 6 ka and 9 ka. In particular, the relevance of P-ann for Picea and Pinus increases and has become the main determinant. This change in the climate tree pollen relationship parallels a widespread tree pollen decrease in north-central China and the eastern Tibetan Plateau. We assume that this is at least partly related to vegetation climate disequilibrium originating from human impact. Increased atmospheric CO2 concentration may have permitted the expansion of moisture-loving herb taxa (Cyperaceae and Poaceae) during the late Holocene into arid/semi-arid areas. We furthermore find that the pollen climate relationship between north-central China and the eastern Tibetan Plateau is generally similar, but that regional differences are larger than temporal differences. In summary, vegetation climate relationships in China are generally stable in space and time, and pollen-based climate reconstructions can be applied to the Holocene. Regional differences imply the calibration-set should be restricted spatially.}, language = {en} } @article{Zhu2017, author = {Zhu, Jinshan}, title = {Assessing China's price review policy on Clean Development Mechanism projects}, series = {European Journal of Law and Economics}, volume = {43}, journal = {European Journal of Law and Economics}, publisher = {Springer}, address = {New York}, issn = {0929-1261}, doi = {10.1007/s10657-016-9550-3}, pages = {285 -- 316}, year = {2017}, abstract = {The Kyoto Protocol's Clean Development Mechanism (CDM) allows developed countries to meet part of their obligational emission reductions by carrying out emission reduction projects in developing countries.

With a theoretical model and a coherent empirical study, the present study shows that the price floor imposed by China's price review is more likely to protect those domestic project owners against price discrimination, rather than to distort the CDM market. Nevertheless, China's price review has its own flaws. Although a regression study shows month of approval, types of projects and location of project can explain 55\% of price floor designation, the operation of price review remains quite random and unpredictable in individual cases. This would bring extra bureaucratically uncertainty on its way to curb market uncertainty. Its function can be fulfilled by alternative policy tools with better economic efficiency and legal legitimacy, such as mandatory price disclosure and trading forum, which doesn't have such drawback, but still be able to alleviate possible price discrimination in individual cases.}, language = {en} }
