Regional Financial Development Scale, Structure, Efficiency and Economic Growth: A Dynamic Analysis

With the panel data in 29 provinces and cities in China from 1991 to 2007, this paper applies the dynamic panel data model to empirically explore the relationships between financial development scale, structure, efficiency and economic growth. The results show that after controlling other factors, financial scale has significantly positive impact on economic growth in middle and western regions but negative in eastern region; while financial structure and efficiency exhibit significantly positive effects only in eastern region. This paper then adopts the model of panel data VAR to investigate the causality relationships between them. It finds that the “demand-following” phenomenon between financial development and economic growth occurs in eastern region, the “supply-leading” phenomenon happens in western region, and yet the middle region shows no obvious pattern of financial development.

A Research of Constructing Regional Financial Ecological Main Bodies’ Indicator System and Competitiveness Evaluation

Based on the statistics of 29 provinces of China from 1996 to 2008, regional financial ecological main bodies’ indicator system is constructed and their evaluation of competitiveness is studied. For the selection of reasonable evaluation indicators, reliability and validity tests could determine the evaluation method and corresponding indicators. Then the competitiveness of 29 provinces’ financial ecological main bodies is listed after quantification. Results suggest that mature financial ecological main bodies mostly located in East China, Beijing, Shanghai and Guangdong are at the top. Undeveloped financial ecological main bodies concentrated in West China, Qinghai, Ningxia and Guizhou is the poorest. Financial ecological main bodies with potential are most common type of the provinces in Central China. Key words: Financial ecological main bodies; Competitiveness; Principal component analysi

The Study on Financial Eco-environment Index System Structure and Competitiveness Evaluation of Changzhutan Urban Agglomeration

According to the 2003 - 2009 statistical data of eight cities in Changzhutan urban agglomeration, we have taken a deep study on financial eco-environment index system structure and competitiveness evaluation. First of all, we choose the reasonable evaluation indexes and tested the reliability and validity of the indexes, so as to determine the method and model of evaluation indexes. Then, we estimated the local financial eco-environment competence of the eight cities, and compared the results. Results show that: the core city-Changsha has mature financial eco-environment; Zhuzhou and Hengyang have the developing financial eco-environment; and the main form of the rest cities’ financial eco-environment is backward.Keywords: Financial eco-environment; Competitiveness; The principal component analysi

The Anti-Inflammatory Effects of a Yin Zhi Huang Soup in an Experimental Autoimmune Prostatitis Rat Model

The present study aimed to investigate the therapeutic effects of the Chinese herbal medicine Yin Zhi Huang soup (YZS) in an experimental autoimmune prostatitis (EAP) rat model. In total, 48 rats were randomly divided into the following four groups (n=12/group): saline group, pathological model group, Qianlietai group, and YZS group. We determined the average wet weight of the prostate tissue, the ratio of the wet weight of the prostate tissue to body weight, tumor necrosis factor-alpha (TNF-α) levels in the blood serum, the expression of inducible nitric oxide synthase (iNOS) in the rats’ prostate tissues, and the pathological changes in the prostate tissue using light microscopy. YZS reduced the rats’ prostate wet weight, the ratio of the prostate wet weight to body weight, and TNF-α levels in the blood serum and inhibited the expression of iNOS in the rats’ prostate tissues (P<0.05). Following YZS treatment, the pathological changes in the rats’ prostates were improved compared with those in the model group (P<0.05). Furthermore, YZS treatment reduced inflammatory changes in the prostate tissue. It also significantly suppressed proinflammatory cytokines, such as TNF-α, and chemokines, such as iNOS, in the rat model of EAP

Relationship between Environmental Pollution, Environmental Regulation and Resident Health in the Urban Agglomeration in the Middle Reaches of Yangtze River, China: Spatial Effect and Regulating Effect

The Healthy China 2030 Initiative is closely related to the coordinated development between national health, economy, and society. This major move demonstrates China&rsquo;s active engagement in global health governance and in the fulfillment of the 2030 Agenda for Sustainable Development (SDGs). Based on Grossman&rsquo;s health production function, this paper introduces key factors such as environmental pollution and environmental regulation to empirically investigate the regulating effect of environmental regulation, as well as the spatial spillover of environmental pollution and environmental regulation acting on resident health. We examine these effects by using the panel data of 28 cities of the urban agglomeration in the middle reaches of the Yangtze River (UAMYRY) between 2009 and 2019. The results show that: (1) Environmental pollution brings a loss to resident health. Among the urban agglomerations, the circum-Changsha&ndash;Zhuzhou&ndash;Xiangtan urban agglomeration (CCZXUA) and the Poyang Lake urban agglomeration (PLUA) have a much lower health effect of environmental pollution than the Wuhan urban agglomeration (WUA). (2) With the growing intensity of environmental regulation, the negative effect of environmental pollution on resident health will gradually decrease. Regionally, the environmental regulation in the CCZXUA has the best effect on residents&rsquo; health, followed by the WUA and the PLUA, which have the worst. (3) As a whole, the spatial spillover of environmental regulation and pollution has a significant impact on residents&rsquo; health, and the spatial spillover effect between urban agglomerations is stronger than that between cities in each urban agglomeration. The conclusions remain robust with various tests such as replacing control variables, introducing lagged explanatory variables, and considering endogeneity. Based on robust empirical evidence, several specific region policy suggestions, including rolling out proper environmental regulation policies, and establishing a linking mechanism of environmental management, were put forward to improve the environmental pollution state and resident health level of the UAMYRY

Single photon emitters with polarization and orbital angular momentum locking in monolayer semiconductors

Excitons in monolayer transition metal dichalcogenide are endowed with intrinsic valley-orbit coupling between their center-of-mass motion and valley pseudospin. When trapped in a confinement potential, e.g., generated by strain field, we find that intralayer excitons are valley and orbital angular momentum (OAM) entangled. By tuning trap profile and external magnetic field, one can engineer the exciton states at ground state, and realize a series of valley-OAM entangled states. We further show that the OAM of excitons can be transferred to emitted photons, and these novel exciton states can naturally serve as polarization-OAM locked single photon emitters, which under certain circumstance become polarization-OAM entangled, highly tunable by strain trap and magnetic field. Our proposal demonstrates a novel scheme to generate polarization-OAM locked/entangled photons at nanoscale with high degree of integrability and tunability, pointing to exciting opportunities for quantum information applications.Comment: 10 pages, 5 figure
