摘要：
An enterprise's capability is based on the quantity and collocation pattern of the heterogeneous resources it possesses. Innovation resources are the source of enterprise innovation capability. However, there is still a "black box" problem of the impact of the intensity of government support on enterprise innovation. Therefore, it is necessary to study high- or low-level enterprise innovation capability by combining the internal and external factors of the enterprise-the background characteristics of R&D personnel and the degree of government support. Based on the configuration perspective, this study uses the qualitative comparative analysis (fsQCA) method to conduct a comparative analysis of the innovation capabilities of enterprises in five time windows over six years with the longitudinal database of China's industrial enterprises whose operating income exceeds RMB 20 million from 2010 to 2015. This paper summarizes two ways of realizing high-level enterprise innovation capability: female and highly educated R&D personnel type, and highly educated R&D personnel and high government investment type. The enterprise innovation capability is affected simultaneously by multiple conditional variables, and the impact of each conditional variable on enterprise innovation capability has a trend. Further, it analyzes the impact of every antecedent variable comparing high- to low-level enterprise innovation.

摘要：
Abstract Social fairness and economic recovery stimulation constitute crucial challenges in countries all around the world, and tourism development has enormous potential for balancing efficiency and fairness. Based on the panel data at city level in Yangtze River Delta Region, China, this study uncovered the role that tourism development plays in economic growth and urban–rural income gap by adopting the dynamic SYS‐GMM model. In addition, the moderating effect model was employed to concentrate on the moderating role of urbanization on the relationship between tourism development and economic growth as well as urban–rural income gap. The main conclusions are as follows. First, tourism development does not only promote economic growth, but it also narrows the urban–rural income gap. Second, when it comes to the dynamic effect generated by tourism development, the economic growth‐promotion effect is stronger than the urban–rural income gap‐inhibiting effect. Third, urbanization can enhance the impact of tourism development on economic growth and the reduction of urban–rural income gap.
摘要：
This study examines the optimal pricing and disclosure strategies of sellers who possess private quality information. We consider two market structures, namely, monopoly market and duopoly market; under each market structure, we further consider two characteristics of consumer preferences for the same product: homogeneity and heterogeneity. How competition and whether consumers are heterogeneous affects sellers' disclosure strategies, and profitability is the focus of our attention. Interestingly, we show that the monopolistic seller's profit is likely to increase as the disclosure cost, which is not possible in a competitive environment. We indicate that when consumers are homogeneous, sellers can obtain higher returns and are more likely to engage in quality disclosure. Finally, we show that when the market is filled with homogeneous consumers, competition always increases the motivation for sellers to engage in quality disclosure. However, when the market is filled with heterogeneous consumers, competition actually hinders sellers from engaging in quality disclosure when the cost of disclosure is low. Our results help company managers in making better disclosure and pricing strategies.

摘要：
Manufacturing intelligence is an important starting point to achieve high-quality economic growth. Based on the non-radial and non-angular DEA-SBM model, combined with the Malmquist index method, this paper calculates the total factor productivity and green total factor productivity of 286 prefecture-level cities in China, which are used as the indicators of high-quality economic growth. At the same time, the proxy variables of manufacturing intelligence are further constructed, and the impact of intelligent manufacturing on high-quality and energy-efficient economic growth is empirically analyzed. It is found that intelligent manufacturing significantly promotes China’s high-quality and energy-efficient economic growth. Productivity is further decomposed into specific indicators such as technical efficiency, technological progress, pure technical efficiency, pure technical progress, scale efficiency and scale technology, and the mechanism of intelligent manufacturing is analyzed from multiple angles. The research finds that manufacturing intelligence improves the total factor productivity through technological progress effect. Green total factor productivity has been improved through the improvement of technical efficiency effect, but the development of intelligence has brought new challenges to China's labor market. In order to further develop the potential of intelligence, it is necessary to further improve the enterprises’ scale efficiency, while increasing the research and development of energy technology.
摘要：
With the convergence of China's "entrepreneurial society" and the "digital age," part-time entrepreneurial behavior (PEB) has received widespread attention as a new form of labor relations and entrepreneurial paths. Entrepreneurial self-efficacy (ESE) is an important indicator of entrepreneurs' confidence in their skills and in coping with uncertain entrepreneurial challenges. However, studies on how ESE affects different types of PEB have not been thoroughly carried out. To fill the existing research gap, the primary objective of this paper is to thoroughly investigate the individual impact of three key factors, namely organizational management self-efficacy (OMSE), opportunity development self-efficacy (ODSE), and risk-taking self-efficacy (RTSE), on economic profit-driven part-time entrepreneurial behavior (EPEB) and self-value-driven part-time entrepreneurial behavior (SPEB), respectively. Based on the "cognition-environment-behavior" logic of triadic reciprocal determinism, this study also aims to examine the moderating effect of entrepreneurial resources (ERs) and attempt to understand how external factors regulate internal factors (OMSE, ODSE, and RTSE) to form the results of EPEB and SPEB. This study adopted a quantitative research approach with a questionnaire survey, taking 457 part-time entrepreneurs in 11 major cities as subjects. The main results show that (1) OMSE and ODSE have a positive effect on EPEB, while RTSE has an inverted U-shaped effect on it; (2) ODSE and RTSE have a positive effect on SPEB, and OMSE has an inverted U-shaped effect on it; and (3) ERs play a positive moderating role in the above processes. The results can not only effectively guide part-time entrepreneurs in PEB but also provide a reference for the government to improve part-time entrepreneurship policies.

摘要：
Rural land consolidation projects (RLCPs) have become one of the largest organized human activities to change land use patterns and impact terrestrial ecosystems, and it may also be an important precondition to improving ecosystem service value (ESV). Evaluating the change in ecosystem service value (ESV) is an important basis for measuring the effectiveness of RLCPs. Therefore, this paper, taking RLCPs implemented at County Level in Hubei Province, China, as an example, uses the improved ESV evaluation model to analyze the spatial differentiation of ESV change in RLCPs and then adopts geographic detectors and a geographically weighted regression model to identify the dominant factors affecting the ESV change in RLCPs. The results showed that (1) although RLCPs make the unevenness of land use obvious, they reduce the complexity of land use evidently and improve the dominance of land use significantly; (2) The ESV of RLCPs in 71 counties of Hubei Province increased, with an average increase of USD 2.37 x 10(7) a(-1). The ESV increase is large in central Hubei, while small in eastern and western Hubei. However, the increase rate of ESV is high in eastern and central-north Hubei, while low in western and central-south Hubei. This indicates that RLCPs can effectively promote ESV, but there are significant regional differences, and (3) the ESV increase is positively correlated with GDP and construction scale, but negatively linked with investment and per capita income of rural residents. The ESV increase rate is negatively associated with cultivated land proportion and land use diversification index change, but it is positively related to the change in the land use evenness index. However, their driving effects have significant spatial heterogeneity.

摘要：
Research on urban development patterns and urban sprawl in the Yangtze River Economic Belt (YREB) has received wide attention. However, existing research has always made use of statistical data, which are not often available. Considering the high availability of satellite data, this study attempts to combine two satellite-acquired indexes, including urban area and night-time light, to evaluate the urban development of the YREB during 2012–2019. The methods included using growth index, rank-size law, and the Markov transition matrix, as well as constructing urban night-time light density and unbalanced index of night-time light, derived from the Gini Index. Some important patterns were revealed. Firstly, the three reaches (Upper Reaches, Middle Reaches, and Lower Reaches) in the YREB have all shown rapid growth in urban area and night-time light, and they all have increased in urban density. Secondly, from the perspective of regional disparity, the Upper Reaches have the highest growth rate of the urban area, while the Middle Reaches have the highest growth rate of night-time light; and the Upper Reaches have more urban sprawl, while the Middle Reaches have shown more compact growth. Thirdly, higher urban density is related to more balanced development across cities. Our study suggests new knowledge can be obtained by combining the two indexes for understanding urban development in the YREB.

摘要：
Foliar application of selenium (Se) fertilizer has been widely used in the production of Se-rich rice. However, the effect of Se-nanoparticles (SeNPs) fertilizer on rice quality remains largely unknown. Two bioSeNPs fertilizers were applied at different Se concentrations to explore the effect of the foliar application of SeNPs fertilizer on various rice grain qualities. The results showed that Se treatments resulted in 1.93–9.09 and 1.89–7.73 folds of total Se contents in brown and polished rice relative to the CK, respectively. Moreover, the Se treatments led to 1.04–2.33 folds increases in Cd contents, 14.6–26.4% decreases in As contents, a 13.9–16.7% reduction in Cr contents and no changes in Pb contents to that of the CK in rice grains. In addition, SeNPs exhibited no obvious impact on rice eating and cooking quality, and only the XY1 treatment could slightly improve the fatty acid content. Interestingly, Se treatments enhanced the contents of more than half of volatile organic compounds in brown rice. In general, SeNPs fertilizer XY at 6.4 g/ha was identified as the optimum choice for improvement in grain Se contents and grain qualities.
摘要：
With the cyclical development of emerging technologies, in reality, the evolution dynamics of their innovation networks will inevitably show obvious time attributes. Numerous network analyses of real complex systems usually focus on static networks; however, it is difficult to describe that most real networks undergo topological evolutions over time. Temporal networks, which incorporate time attributes into traditional static network models, can more accurately depict the temporal features of network evolution. Here, we introduced the time attribute of the life cycle of emerging technology into the evolution dynamics of its innovation network, constructed an emerging technology temporal innovation network from a temporal network perspective, and established its evolution model in combination with the life cycle and key attributes of emerging technology. Based on this model, we took 5G technology as an example to conduct network evolution simulation, verified the rationality of the above model building, and analyzed the cyclical evolution dynamics of this network in various topological structures. The results show that the life cycle of emerging technology, as well as multiple knowledge attributes based on the key attributes of emerging technology, are important factors that affect network evolution by acting on node behaviors. Within this study, we provide a more realistic framework to describe the internal mechanism of the cyclical evolution of emerging technology innovation network, which can extend the research on innovation network evolution from the single topological dynamics to the topological–temporal dynamics containing time attributes and enrich the research dimensions of innovation network evolution from the perspective of temporal evolution.

摘要：
China's flat panel display industry boasts the largest scale worldwide and injects sustained momentum into the global flat panel display supply network. Flat panel displays being exchanged in international flows are deeply characterized by each Chinese province, forming the Chinese overseas flat panel display supply network. Network science is applied to investigate the emergent topology and disruption risk propagation of supply networks. Therefore, this study first constructs weighted and directed Chinese overseas flat panel display supply networks from 2017 to 2021 to investigate the visible risks of these networks by macroscopic and microscopic structures. Second, the hidden risk sources are revealed in supply networks using the proposed risk propagation model in supply, demand, and cooperation disruption scenarios related to China's zero-COVID policy. The finding reveals that the visible supply risks are focused on the Yangtze River Delta region and Guangdong province, and the demand risks for flat panel d0069splays are also concentrated in these provinces. China's supply of flat panel displays to the USA is gradually shifting to Southeast Asian countries. Additionally, the hidden risks are mainly concentrated in the eastern coastal provinces of China. The hidden cooperation risks are focused between Guangdong province and the USA, and South Korea. These findings will be helpful for determining which provinces or countries are risky sources or for offering an early warning mechanism and helpful for a more resilient and robust supply network.

Dynapenia;anthropometric measurements;cut-off values;receiver operating characteristic curve analysis;the five times sit-to-stand test
摘要：
PURPOSE: This study evaluated whether anthropometric measurements and the five times sit-to-stand test could be used to identify dynapenia. The cut-off values of accurate screening tools for identifying dynapenia were also established. MATERIALS AND METHODS: This was a cross-sectional study conducted on individuals ≥ 60 years old (N = 529). All participants underwent handgrip strength measurement, anthropometric measurements and the five times sit-to-stand test. The participants whose handgrip strength was < 28 kg for men and < 18 kg for women were considered to have dynapenia. The association between the recorded variables and dynapenia was determined using logistic regression, and cut-off values were established by performing the Receiver Operating Characteristic curve analysis. RESULTS: The prevalence of dynapenia was 35.42% in men and 25.61% in women. For males, both calf circumference (≤ 35.2 cm) and the five times sit-to-stand test (≥ 14.6 s) could be used as accurate tools for dynapenia. For females, only the five times sit-to-stand test (≥ 11.8 s) had sufficient accuracy to be used as a screening tool for dynapenia. CONCLUSIONS: The five times sit-to-stand test was an accurate screening tool for identifying dynapenia. The calf circumference could be only used as a screening tool in males.

摘要：
The "last-mile problem" of public transportation is one of the main obstacles affecting travelers who choose to utilize public transport. Although autonomous vehicles (AVs) have made much progress, they have not been officially put into commercial use. This paper adopts stated preference experiments to explore the impact of shared AVs on the last-mile travel behavior of metro users and takes Wuhan as an example for case analysis. First of all, this paper establishes a structural equation model (SEM) based on the theory of planned behavior to explore latent psychological variables, including travelers' attitudes (ATTs), subjective norms (SNs), perceived behavior control (PBC), and behavioral intention of use (BIU) toward AVs. These latent psychological variables are incorporated into the latent class (LC) logit model to establish a hybrid model with which to study the factors and degree of influence on the travel mode choices of travelers for the last mile of their metro trips. The results show that travelers have preference heterogeneity for the travel mode choices for the last mile of metro trips. Through the analysis of LCs, education, career, and income significantly impact the classification of LCs. The latent psychological variables towards AVs have a significant impact on the travel behavior of respondents, but the impacts vary among different segments. Elastic analysis results illustrate that a 1% increase in the travel cost for shared AVs in segment 1 leads to a 7.598% decrease in the choice probability of using a shared AV. Respondents from different segments vary significantly in their willingness to pay for their usage, and the value of travel time for high-income groups is relatively higher.
摘要：
This research analyses the relative efficacy of gold price, financial market, and stock exchange hedging against sectoral and industry-level global stock market returns. Incorporating Gold into equity-based asset allocation techniques and assessing the stock market and financial sector during the COVID-19 epidemic is one way to diversify your portfolio and reduce risk. After orthogonalizing raw returns concerning a robust collection of relevant universal variables, we conduct our analysis inside a bivariate GARCH(p, q) framework. To further assess ideal portfolio proportions and the efficacy of hedging methods, we expand the volatility spillovers study by calculating the optimal weights for a minimal risk portfolio and determining the hedge ratio. In high-volatility environments, our results show which financial market and stock exchange sectors and industries investors should prioritize to minimize the risk and maximize reward. Use of country-specific macroeconomic variables indices to supplement the worldwide index, (3) separate analysis for the COVID-19 first wave due to the existing argument that the pandemic raises unexpected market events and our early data showing co-movement among the three unpredictability metrics during the pandemic. These findings have important implications for portfolio entrepreneurs and business investors looking to buy international equities.

Objectives: This study aimed to investigate the associations between social isolation, loneliness, and motoric cognitive risk syndrome (MCR) among older adults in China.Methods: Data were obtained from the China Health and Retirement Longitudinal Study in the 2011 and 2015 waves. Social isolation and loneliness were measured by an index and an item, and MCR was defined as subjective cognitive complaints and slow gait. Multivariable logistic regression analyses were performed to examine the associations between social isolation, loneliness, and MCR by gender.Results: Of 3251 eligible participants, the incidence of MCR was 10.03%. Social isolation and loneliness were not significantly associated with incident MCR in men. Loneliness was positively associated with incident MCR in women (OR: 1.45, 95% CI: 1.05, 2.01), while social isolation was not.Conclusions: Loneliness is associated with incident MCR among female older adults in China. More attention is advised to be paid to loneliness among female older adults, to hold promise for the prevention and reduction of MCR.
摘要：
This study focuses on two types of online advertising: mass advertising and targeted advertising. First, models for equilibrium pricing and profit influencing decisions are constructed based on asymmetric cost efficiency and converter preference. Second, game theory is used to analyze two scenarios: competitive enterprises participating simultaneously in both mass advertising and targeted advertising, and only one enterprise participating in targeted advertising. The main research findings are as follows: 1) Between the two advertising modes, enterprises can realize Pareto optimization more easily when engaging in targeted advertising. 2) In terms of cost efficiency, enterprises with low cost efficiency are more likely to obtain more benefits by participating in targeted advertising. 3) As far as the preference of the converter is concerned, generally speaking, with the increase in converter preference, enterprises with converter advantages will obtain more (or the same) profits than others. 4) Both average price and high price strategy are more sensitive to advertising costs than the preference of the converter. The conclusions of this study provide a theoretical basis for enterprises to advertise and the corresponding best methods.
