树立科技矿政理念改革矿政管理制度——以资源储量消耗计征矿产资源税费

科技矿政理念的基本含义就是努力提高矿政管理的科技含量,遵循地质矿产规律,依靠科技进步显著提升我国矿产资源保护与利用水平.推动科技矿政管理进程,首先要从资源储量管理方面夯实基础,建立健全资源储量实物账户与价值账户.进而改革矿产资源权益分配方式,以资源储量消耗计征矿产资源税费.相应改革矿业权评估制度.     

基于纵向一体化的矿业探采一体化研究

矿业探采一体化本身是探矿主体或采矿企业纵向一体化的过程.探采一体化具有提高资源的利用效率、节约交易费用、降低市场风险、扩大规模效应、提升企业国际竞争力、促进矿业可持续发展的六大优势.受制于我国传统地勘体制和矿业市场环境的限制,我国矿业发展面临着地勘行业严重萎缩,探矿业滞后采矿业,探采不平衡,探采一体化推进缓慢等诸多问题.有效解决这些问题,需要通过明晰政府角色定位、创新机制和体系、优化市场环境,加快推进矿业探采一体化.     

Incorporating textual information in customer churn prediction models based on a convolutional neural network

This study investigates the value added by incorporating textual data into customer churn prediction (CCP) models. It extends the previous literature by benchmarking convolutional neural networks (CNNs) against current best practices for analyzing textual data in CCP, and, using real life data from a European financial services provider, validates a framework that explains how textual data can be incorporated in a predictive model. First, the results confirm previous research showing that the inclusion of textual data in a CCP model improves its predictive performance. Second, CNNs outperform current best practices for text mining in CCP. Third, textual data are an important source of data for CCP, but unstructured textual data alone cannot create churn prediction models that are competitive with models that use traditional structured data. A calculation of the additional profit obtained from a customer retention campaign through the inclusion of textual information can be used by practitioners directly to help them make more informed decisions on whether to invest in text mining.     

Mapping hotel brand positioning and competitive landscapes by text-mining user-generated content

This study uncovers hotel brand positioning and competitive landscape mapping by text-mining user-generated content (UGC). Rather than relying on a single dimension of consumer evaluation, the current study detects brand attributes by using both customer preferences as well as perceptual performance to develop meaningful insights. For this, the study combines content analysis and repertory grid analysis (RGA) to answer three key research issues. 111,986 hotel reviews from two biggest Chinese cities are used to explore and visualize the competitive landscape of six selected hotel brands across three hotel categories. Findings from the study will not only advance the existing literature on brand positioning and competitive landscape mapping but also help practitioners in developing brand positioning strategies to fight competitors within and across hotel categories.

作业成本管理在煤炭企业的应用

随着煤炭市场的国际化和煤炭价格的放开,只有降低生产成本,才能提高我国煤炭企业的经济效益。作业成本管理是一种先进的成本管理模式,国内外一些先进制造型企业及IT企业已经实施了作业成本管理,作业精简和效能提高的作用十分明显。将作业成本管理引入煤炭企业,通过对作业成本管理与煤炭企业结合的适用性研究,提出适合煤炭企业的作业成本管理方案。     

基于数据挖掘技术的企业客户关系管理(CRM)

由于竞争的全球化、需求的拉动和管理理念的更新,使客户关系管理(CRM)得到产生和发展。面对企业海量的数据,如何从其中发现有价值的知识和规律是企业急需解决的难题。数据挖掘技术为此提供了工具和途径。在了解CRM的概念和框架、数据挖掘的各种技术后,还必须了解数据挖掘在CRM中的应用流程和应用的业务领域。     

乡镇企业群落的市场结构、竞争与治理

乡镇企业群落在发展过程中,不同阶段均会出现一些问题,但现阶段广东乡镇企业群落中最普遍的问题就是群落内各个企业合作不足,竞争过度,即出现了局部过度竞争现象。采用梅森等人创立的SCP范式,分析企业群落内的过度竞争现象,提出群落内过度竞争问题的解决,有赖于正式治理、非正式治理及行业协会治理等模式的建立。     

矿法修改应增加对矿权相邻关系制度的内容

相邻关系是传统民法规范相邻不动产之间权利义务关系的一项重要法律制度。本文对矿权相邻关系的基础理论、国内外矿权相邻关系的立法现状进行了论述,针对现实中我国矿权相邻关系亟待法律规范和我国矿权相邻关系法律制度存在的不足,提出了在我国《矿产资源法》等法律法规修改中增加矿权相邻关系相关内容的立法建议。
