本文以浙江为例,在经济增长理论的基础上,建立了县域金融发展与产业集聚区经济增长之间相互作用的内生模型,基于浙江省22县(市)的县级数据,运用面板数据模型对县域金融发展与产业集聚区经济增长的互动关系进行了实证检验,比较了各产业集聚区经济增长的影响因素。研究发现:浙江县域金融发展规模、固定资产投资、实际利用外资与产业集聚区经济增长存在高度正相关关系;金融发展效率对产业集聚区经济增长的检验效果不显著;实际利率对产业集聚区经济增长的影响不显著,提出在执行利率政策时,不能采用金融发展理论中提高利率、解除金融抑制的政策手段。  相似文献

The success of electronic filing services largely depends on their continuance usage. This study examines the factors affecting the continuance usage intention of the online tax filing services in Mauritius. An integrated model comprising Trust Theory and Information System Success Model (ISSM) is applied to assess the continuance usage behaviour of e-filing systems. The model has been extended by adding two additional variables: Perceived Usefulness and Perceived Risk. The model was tested using a sample of 315 users of e-filing services in Mauritius. A structural equation modelling technique using partial least square structural equation modelling verified the hypotheses. The results reveal that the continuance usage intention of an electronic tax filing system is influenced by Perceived Usefulness, User Satisfaction, and Service Quality. However, Perceived Risk does not influence the continuance usage intention of e-filing systems since the importance of Perceived Risk diminishes as trust in the e-service provider increases. The theoretical and practical implications derived from the findings of this study are also discussed. This paper makes several contributions to the literature on electronic tax filing systems.  相似文献

This article looks beyond Z-score and proposes a novel methodological framework to build an all-encompassing indicator of bank stability for individual banks using the optimisation-based ‘benefit-of-the-doubt (BoD)’ approach. Unlike other available approaches, this approach is totally data-driven and generates endogenous weights to aggregate sub-indicators of bank stability and dimensions. Further, the final outcomes are not limited to a scalar measure of bank stability. The unique optimal weights offer valuable policy-relevant insights and highlight the most precarious areas of stability, which demand the immediate attention of the bank's management and the industry regulators for both micro-and macro-level policymaking. Using the data of Indian public sector banks operating in the year 2018, the study illustrates the proposed framework to obtain a holistic indicator of bank stability, defined on 14 ratio sub-indicators and 5 broad dimensions (soundness, asset quality, profitability, management efficiency, and liquidity) of bank stability.  相似文献

The current analysis aims to explore the empirical nexus between financial development, foreign direct investment (FDI) inflow, and employment rate. To attain this aim, we collect 30 years of annual data over the period 1990 to 2019 from South Asian economies and employ the autoregressive dynamic least square (ARDL) model for regression analysis. The implication of the ARDL model was subject to the mixed stationarity status of the series as assessed by unit root testing. The robustness of the analysis was checked by employing the fully modified ordinary least square (FMOLS) and dynamic ordinary least square (DOLS) models. The statistical analysis infers that both financial development and FDI inflow enhance the employment rate in the South Asia region. In addition, the empirical analysis infers that the gross capital formation, economic growth, and export volume have a positive while the population growth rate has a negative effect on the employment rate. The impact of underlying explanatory variables was found significant only in long run. The estimated coefficient values in the case of FMOLS and DOLS models support the direction of the relationship between explanatory variables and employment rate, implying the robustness of the analysis. The findings of the current analysis can be used to devise efficient economic policies to cope with the encroaching issue of unemployment in the South Asia region. This study offers the robustness to existing literature and complements the literature by exploring the underlying arrangement of study to the whole South Asia group.  相似文献

Gang membership is believed to impede success in the legitimate economic market while simultaneously supporting success in the illegal market. We extend the study of the economic effects of gang membership by using a within‐ and between‐individual analytic design, decomposing gang membership into multiple statuses (i.e., entering a gang, continuously in a gang, leaving a gang, and inactive gang membership), examining legal and illegal earnings simultaneously, and accounting for factors endogenous to gang membership that may contribute to economic achievement. By using panel data from 1,213 individuals who participated in the Pathways to Desistance Study to conduct a multilevel path analysis, we find that active gang membership status is unrelated to legal earnings. Alternatively, entering a gang is associated with increased illegal earnings, attributable to changes in delinquent peers and drug use, whereas leaving a gang has a direct relationship with decreased illegal earnings. Our results indicate that the positive economic effect of gang membership (i.e., illegal earnings and total earnings) is short‐lived and that, on balance, the sum of the gang membership experience does not “pay” in terms of overall earnings.  相似文献

Estimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.  相似文献

High-profile events involving police use of force in various cities throughout the US and internationally have garnered enormous media coverage and demonstrated the importance of police-community relations. To date little empirical attention has focused on how such events may negatively impact police officers. Using survey data from 567 officers, this study considers whether perceptions of negative publicity are adversely related to officers’ sense of self-legitimacy (i.e. the confidence they have in their authority). Findings revealed officers who felt less motivated as a result of negative publicity expressed less self-legitimacy. However, the degree to which officers felt their job had become more dangerous as a result of negative publicity was not significantly related to self-legitimacy. These findings increase our understanding of the sources of self-legitimacy and reveal that negative publicity surrounding law enforcement presents a unique challenge to officers’ confidence in their authority, which can have important implications for the community.  相似文献
