2019年1月12日,国务院印发了《关于促进综合保税区高水平开放高质量发展的若干意见》(国发〔2019〕3号,以下简称《若干意见》),推出21项政策措施加快推进制度创新、促进综合保税区(以下简称“综保区”)升级发展。文件出台后,各地综保区围绕“五大中心”的建设目标,在海关及其他相关职能部门的支持下,加强政策宣传,推动改革创新,强化考核评价,努力推动各项政策落地。为了更好地推进综保区高水平开放高质量发展,课题组对江苏省综保区发展情况开展全方位调研,并且以江苏省综保区为例,对当前制约综保区发展的原因,特别是影响《若干意见》实施效果的原因进行了深入分析,按照制度型开放的要求,从管理机制、发展目标、监管模式等角度提出合理建议,探索新时期海关支持综保区高水平开放高质量发展的路径。 相似文献

运用扎根理论探究了企业家创新性社会责任行为的特征及作用机制。基于扎根理论,就企业家微公益行为对其形象评价的影响机制进行了探索性研究。通过深度访谈与二手数据的扎根分析,提出了企业家微公益行为对其形象评价影响的理论框架:企业家微公益行为具有权威性、互动性与多样性,会通过情感和认知两大层面来获取消费者认同感,并影响消费者对企业家微公益行为动机的感知,进而影响其形象评价。该研究是对企业家社会责任理论的有益拓展,同时为希望通过社交网络进行公益活动的企业家提供了实践参考。 相似文献

Energy policy, environmental planning and economic development play a key role in sustainable development. Sustainable development requires suitable and strategic policies satisfying multiple and conflicting objectives. Fuzzy goal programming (FGP) is a well-known approach in multi-criteria decision-making for its practical application. In this article, a FGP approach is proposed to analyse environmental, energy and sustainability goals of India by the year 2030 with reference to the key economic sectors of India. The presented model analyses the improvement opportunities, requirement of efforts and implementation of the sustainable development plans. Numerical illustration is also provided for validation and application of the proposed model. 相似文献

In this paper we examine the question of whether and how municipal landscape plans exert a positive influence on and/or correlate with selected aspects of the landscape. To this end, a representative sample of municipal landscape plans in Germany and a statistical-quantitative evaluation approach are used to uncover correlations between planning and landscape development. As a result, we can show that municipalities which draw up a landscape plan have a higher proportion of natural areas and a lower hemeroby index, i.e. a lower level of human influence. The model also reveals a significant relationship between the quality of the landscape plan as well as its duration of impact and the density of landscape structural elements. It is also determined that municipal landscape plans help protect grassland areas. The indicator-based method provides impulses for the international discussion on the evaluation of plans. 相似文献

The traditional mean–variance approach has been complemented by alternative theories that use risk measures different from standard deviation of returns or involve additional distributional features of returns like skewness and kurtosis. We propose a portfolio choice model that combines different distributional characteristics of the returns in the decision-making making process, considering preferences of investors which are modeled as non-statistical uncertainties of investors using fuzzy theory. We use 20 stocks of the S&P500 from January 2013 to December 2017. We assess the obtained portfolios’ performance, and the diversified behavioral portfolios outperform than the mean–variance portfolio. This methodological proposal can be seen as a strong managerial tool to make investment portfolio decisions. 相似文献

2016年5月《国务院办公厅关于深入推行科技特派员制度的若干意见》发布实施,但其实施效果如何有待验证。构建科技特派员制度实施绩效评估指标体系,利用改进熵值法和官方统计数据,对中国省域科技特派员制度实施绩效进行实证评估,并对评估结果进行聚类分析。结果表明,中国大多数省份科技特派员制度实施绩效水平较低;根据实施科技开发项目、形成利益共同体、服务农民情况、推广服务和扶贫成效5个绩效评估维度,可以将中国内地31个省份划分为5种类型;即使是总绩效水平较高的地区,在科技特派员制度实施绩效方面也存在一些短板。 相似文献

The early stages of innovation involve high levels of uncertainty, leading to it being labelled as the “fuzzy-front end” (FFE). Although openness has been identified as pivotal to innovation performance in the open innovation literature, little effort has been put into exploring its role in the FFE. Specifically, this study examines ‘openness competence’ within the FFE–i.e., the ability of a FFE team to explore, gather and assimilate operant resources from external sources by means of external searches and inter-organisational partnerships. The aim is to investigate the impact of openness competence on front-end uncertainty reduction and service innovation success. Data were obtained from a survey of 122 IT-based service innovation projects implemented by IT service provider firms in Thailand. The results suggest that openness competence positively influences both the degree of uncertainty being reduced during the FFE and the overall success of service innovations. These findings offer several implications for research on open innovation and the FFE as well as encouragement to managers to apply a more open approach to the FFE of their service innovation projects. 相似文献
