中国产业集群问题与对策

产业集群属于生产力空间的一种形式,是企业管理与区域经济的交叉研究领域。本文从企业产业集群的发展现状入手,根据产业集群理论,剖析产业集群的模式和特点,通过对全国主要省区的调查,较为全面地分析了产业集群的发展态势、特征和问题,提出发展产业集群应采用的措施和对策,如纳入政府规划管理范围、资金支持创新和基础设施、优化政府服务、规范市场秩序、加强舆论宣传等。     

扩大行政公益诉讼原告范围的依据及设想

行政公益诉讼制度的产生及发展对社会公共利益的维护起到举足轻重的作用，但目前我国行政公益诉讼制度主要局限于由检察机关牵头所提起的这一行政公益诉讼类型，原告资格范围受到限制。西方国家以“利害关系说”和“私人检察官”等理论依据为依托将行政公益诉讼原告资格逐步扩大，虽然我国《行政诉讼法》中并未明确规定行政公益诉讼制度，但结合我国现行的法律体系发展状况和行政公益诉讼实施成效，我们应将其逐步放宽至社会团体及公民个人。     

工商银行私人银行业务发展刍议

私人银行业务的巨大市场潜力正日益凸显，发展私人银行业务已经成为各大银行争取更多优质客户、为股东创造更大价值的必然选择。工商银行私人银行业务主要存在金融产品缺乏创新、产品配置率和高端客户的认可度均不高、风险管控困难等诸多问题。目前工商银行应该扩大人才优势，进行信贷结构调整以促进业务产品丰富化；强化六大风险管理，加强制度约束与系统控制；建立常态、有效的考核评价制度，充分调动员工的积极性与创造性。     

New morphological features for urban tree species identification using LiDAR point clouds

Urban tree species identification is the basis for studying the urban-environment coordination mechanism at the species level. Although the gradual maturity of remote sensing data and related research including light detection and ranging (LiDAR) provides a good foundation for the realization of this technology, multiple reasons such as cost, data openness, study scope limitations, and weakness of traditional morphological features make such data still challenging to apply to subtropical urban trees with heterogeneous canopy structures and high biodiversity. To address the problem, we developed two large-scale LiDAR morphological features in this research by, 1) modifying the rotate image method based on the axisymmetric structure to make it easier to use, and 2) developing an innovative adaptive ellipsoid method to extract the canopy features of the non-axisymmetric structure effectively. We evaluated the ability of these two morphological features to describe 12 common subtropical urban tree (SUT) species in Hong Kong growing in urban parks and streets, obtaining an accuracy of 88%. And the advantages of the proposed method are demonstrated by comparison with existing LiDAR morphological features and mean decrease accuracy (MDA) analysis. Our results illustrated that the rotate image feature based on the axisymmetric structure did not perform as well as the adaptive ellipsoid feature based on the non-axisymmetric structure in SUT, and the combined application of these two new morphological features got further accuracy improvement. The method proposed in this study had significant advantages in terms of accuracy, the number of species included, and generalisation capability compared to existing studies on the identification of subtropical urban trees.
