Innovation Institution and Spatial Transfer of Energy Industry: The Case of Jiangsu Province, China

This study aims to explore the effect of innovation institution on spatial transfer of energy industry in Jiangsu, China. We focus on the disparity of innovation and energy industry, and analyze the spatial transfer difference in different types of energy industry, rather than view energy industry as a whole. The study demonstrates the spatial change of energy industry at regional level and maps the spatial pattern at city level. The study chooses intellectual property rights (IPRs) protection intensity, authorization patents and local research and development (R&D) investment as the proxy of innovation. Using official data and employing panel fixed-effect model at city-industry level, we conclude (a) innovation abilities significantly influence the spatial transfer of energy industry in Jiangsu. Especially, due to the different time, IPRs protection, patent counts, and R&D investment have different effects on different regions in Jiangsu; (b) 2010 is an important turning point for energy industry development in Jiangsu, and after 2010, the energy industry begins to shift to the middle and northern Jiangsu, whereas the spatial pattern of energy industry in coastal cities is basically unchanged; (c) there is a great difference between the regions in Jiangsu Province, and industrial upgrading has not been achieved in northern Jiangsu

Impacts of reduced inequalities on quality education: Examining the relationship between regional sustainability and higher education

Although the United Nations’ Sustainable Development Goals (SDGs) advocate, through SDG 4 and SDG 10, equitable quality education and the reduction of inequalities within and between countries, respectively, few studies have examined how inequalities in regional sustainability influence higher education. Therefore, this study aims to examine the relationship between regional sustainability and higher education in China using fixed-effects panel modelling. A systematic force framework showing how regional sustainability drives higher education was constructed from economic, social, and environmental perspectives, and the endogeneity in the process of how regional sustainability affects higher education was explored by introducing one-year lagged values as instrumental variables. Our results show that regional sustainability has a significant impact on higher educational attainment in China, with differing effects in the eastern, central, and western regions, respectively. In central China, economic sustainability plays a significant positive role in higher educational attainment; in the western region, economic and social sustainability have stronger positive effects, while environmental sustainability has significantly negative effects. In terms of policy implications, our findings can be used to support regional development policies to promote regional higher education

Large-scale enterprises, social capital and the post-disaster development of community tourism: The case of Taoping, China

This study explores how large-scale enterprises build and mobilise social capital with intra- and inter-community actors to stimulate the post-disaster development of community tourism. Based on in-depth interviews, this case study was conducted in Taoping, China. The findings show that large-scale enterprises integrated bonding social capital created through engaging with Taoping villagers with bridging social capital developed through inter-community collaborations to facilitate the post-disaster development of community tourism. This study focuses on the dynamics of interactions between large-scale enterprises, intra- and inter-community actors. It contributes to providing a deeper understanding of the significance of large-scale enterprises for the post-disaster development of community tourism through the lens of social capital

Mode Repulsion and Mode Coupling in Random Lasers

We studied experimentally and theoretically the interaction of lasing modes in random media. In a homogeneously broadened gain medium, cross gain saturation leads to spatial repulsion of lasing modes. In an inhomogeneously broadened gain medium, mode repulsion occurs in the spectral domain. Some lasing modes are coupled through photon hopping or electron absorption and reemission. Under pulsed pumping, weak coupling of two modes leads to synchronization of their lasing action. Strong coupling of two lasing modes results in anti-phased oscillations of their intensities.Comment: 13 pages, 4 figure

Finite dimensional integrable Hamiltonian systems associated with DSI equation by Bargmann constraints

The Davey-Stewartson I equation is a typical integrable equation in 2+1 dimensions. Its Lax system being essentially in 1+1 dimensional form has been found through nonlinearization from 2+1 dimensions to 1+1 dimensions. In the present paper, this essentially 1+1 dimensional Lax system is further nonlinearized into 1+0 dimensional Hamiltonian systems by taking the Bargmann constraints. It is shown that the resulting 1+0 dimensional Hamiltonian systems are completely integrable in Liouville sense by finding a full set of integrals of motion and proving their functional independence.Comment: 10 pages, in LaTeX, to be published in J.

The brezis-ekeland-nayroles minimization principle with mixed finite element method for elastoplastic dynamic problems

We propose a modification of the Hamiltonian formalism which can be used for dissipative systems, the Brezis-Ekeland-Nayroles principle. The formalism is specialized to the standard plasticity in small strains and dynamics. We apply it to solve the classical problem of a thin tube in plane strain subjected to an internal pressure. The continuum is discretized with mixed finite elements

Transport development, intellectual property rights protection and innovation: The case of the Yangtze River Delta Region, China

The links between transport development and economic growth have been widely discussed in the field of transport governance and economics. However, the existing studies have not included an institutional variable when exploring the role of transport development in innovation disparities within a region. In order to fill the research gap, this paper examines whether transport development and the institution of intellectual property rights (IPRs) can assist in understanding disparities between cities in terms of innovation, using the Yangtze River Delta Region (YRDR) as a case study. The impact mechanism is twofold. Firstly, transport development can affect institutions, including IPRs protection, which in turn has an influence on innovation. Secondly, evidence from existing economic literature suggests a link between transport development and innovation through economic agglomeration, production factors and industrial flows. We first employ ordinary least squares (OLS) regression to test the basic associations between transport development and innovation. We then apply two-stage least squares (2SLS) regression analysis to address endogeneity and add a spatial model to examine neighbour effects. The findings show that IPRs protection has a positive effect on patenting and research and development (R&D), while the roles played by transport development stock and density in patenting and R&D are more mixed. Moreover, our findings on neighbour effects show that agglomeration economies exist in the YRDR. These findings have important policy implications regarding urban agglomeration for both the YRDR specifically and China overall
