Assessment of the sustainable development of rural minority settlements based on multidimensional data and geographical detector method: A case study in Dehong,China

In a developing country, paying attention to the sustainable development of rural areas is conducive to the development of the entire country. Ethnic minority areas are an important part of China's economic and social development. Owing to a lack of relevant statistical data, most previous studies in this area have focused on the sustainable development of rural areas or the development of ethnic minorities, but have not studied the sustainable development of rural ethnic minorities. The development of rural ethnic minorities is worthy of attention. In this study, we took Dehong as the study area. First used toponyms to accurately identify the rural minority areas and then calculated a grid of settlement density. Second, we considered the digital number (DN) value of the visible infrared imaging radiometer suite (VIIRS) as a measure of the development of the region and digital elevation model (DEM), net primary productivity (NPP), normalized difference vegetation index (NDVI), and gross domestic product (GDP) data as the indicators of terrain, climate, ecological, and economic factors, respectively. Finally, linear regression and the geographical detector method were used to determine the weight of the factors for constructing a sustainable development index (SDI) to quantitatively analyze the sustainable development and influencing factors of each minority nationality. The factors evaluated using linear regression and the geographical detector method were ranked as follows: NDVI > elevation > GDP > slope > NPP > settlement density. The results demonstrate that of the five main ethnic minorities in Dehong, Dai and Jingpo have higher SDI, followed by Achang, Lisu and De'ang. In addition, we provide some suggestions for ethnic minorities in Dehong.     

中间品进口多样化、企业创新与工资水平

基于2000-2006年中国制造业企业数据库以及进出口海关数据库的匹配数据引入企业创新机制效应检验中间品进口多样化的工资溢出效应。研究表明中间品进口多样化、企业创新均能显著提高企业的工资水平。进一步考察企业的出口状态、所有制结构及企业所属地区差异后发现中间品进口多样化对出口企业、外资企业以及东部地区企业的工资影响更为显著。分位数回归结果进一步显示中间品进口多样化及企业创新对工资分布高分位企业的工资影响更为显著。基于中介效应模型的传导机制检验，认为中间品进口多样化通过节约成本、提升生产率及企业创新影响中国制造业企业工资水平的利润共享机制存在。在控制成本效应及生产率效应两种机制之后，企业创新成为中间品进口多样化作用于企业工资的新机制。     

Asymptotics for large claims reinsurance in a time-dependent renewal risk model

Abstract

We study the asymptotic tail behaviour of reinsured amounts of the LCR and ECOMOR treaties under a time-dependent renewal risk model, in which a dependence structure is introduced between each claim size and the interarrival time before it. Assuming that the claim size distribution has a subexponential tail, we derive some precise asymptotic results for both treaties.     

我国快速消费品行业营销渠道研究

快速消费品是指使用周期短,重复购买频率高的消费品。我国是人口大国,随着人民生活水平的提高与物质需求的增长,快速消费品已成为支撑我国经济发展的重要行业,同时行业竞争也愈加激烈。虽然我国快速消费品行业发展形势良好,但其中存在的问题不可忽视,营销渠道作为企业与消费者之间的纽带和桥梁,逐渐成为快速消费品行业中管理问题的核心。针对我国快速消费品营销渠道中产生的冲突、渠道窜货、终端销售的管理不善等问题,企业应立足自身情况,强化对渠道的控制与管理,统筹协调好与经销商的合作关系,减少渠道冲突的产生,提高终端销售的服务质量,保证快速消费品行业的可持续发展。     

利益导向视角下医患关系的提升对策研究

改善医患关系作为医疗改革过程中的重要内容受到社会的持续关注。本文将医患关系中的利益相关主体分为直接相关主体以及间接相关主体。对相关主体从各自利益导向出发,阐述医患关系改善过程中的利益得失、矛盾冲突。并以此为出发点提出改善医患关系的对策建议。本文认为,在处理医患关系时应紧抓最直接相关主体的利害关系,兼顾处理其他利益相关主体的利益冲突,才有助于实现医患关系上的纳什均衡,从而协调医患关系。     

Non-traded goods and optimal trade policy in a cash-in-advance economy

This paper develops a standard trade model of a small open monetary economy with two traded and one non-traded goods. Money is introduced through a generalized cash-in-advance constraint where the share of goods purchases that must be made using cash, varies across sectors. We find that free trade may be harmful so that alternative policy instruments may be considered to improve welfare. In addition, we study and compare the optimal tariff formula and the optimal consumption tax structure. In the presence of a monetary distortion of the non-traded good, a consumption tax may not Pareto dominate a tariff although the latter bears an additional production burden. This corroborates the theory of second best.     

垂直专业化分工体系下贸易波动的行业差异性研究

本文计算了中国、日本、美国、英国等国各个部门出口波动情况,同时借助垂直专业化比率(VSS)这一指标衡量了各个部门参与垂直专业化分工的程度。测算结果表明:以其他商业服务(OCS)为典型代表的服务贸易相比于货物贸易尤其是高端货物贸易较少地参与了垂直专业化生产,服务贸易尤其是其他商业服务贸易以及传统货物贸易在国际金融危机中表现出较好的稳定性。     

公共租赁住房混合供应模式——实施层面战略的构建

本文以管理工程的视角结合公共经济学理论,分析了当前公租房建设实施过程中的困扰及其原因,指出问题源于对公租房这一公共产品在概念上的定义偏差,由于这一偏差,进而引起了实施层面的战略矛盾.文章认为公共住房供应并非狭义上的物理形态住房的供应,而更多的是指政府住房保障服务的供应,鉴于社会个人私有住房出租市场的现实存在,有可能通过...     

Exploring customer engagement in the product vs. service context

Though customer engagement (CE) is heralded as a strategic organizational imperative, empirically derived insight into its nomological network remains sparse. Extending existing research, we therefore test service-dominant logic-informed CE vis-à-vis its key antecedents of knowledge sharing and learning, and its consequences of customer cocreation and relationship quality. We also envisage the existence of CE-based differences across physical goods (versus service) contexts, leading us to include the nature of the offering (good vs. service) as a moderating factor in our model, making a novel contribution. To test the model, a survey was conducted in the tangible sports goods (i.e., sports retail) and -service (i.e., sports club) contexts. The findings substantiate a positive effect of customer learning and knowledge sharing on CE, thus empirically validating conceptual literature-based claims. In addition, CE was found to exert a favorable effect on customer cocreation and relationship quality. Moreover, the results confirm our hypothesized moderating effect by revealing the framework’s stronger associations for service- (vs. product-based) CE. We conclude by discussing key implications that arise from our analyses.     

现代中国海关货物贸易统计主流地位的回顾与展望——海关系统外两代统计学人的视角

在当今中国,举凡对货物贸易统计做研究,势必想到海关统计,或者说海关统计就是货物贸易统计的代名词。然而这种对应关系在几十年前并非自然存在,几乎在整个20世纪后半叶,曾有对外贸易业务统计与海关统计平行存在的情形。本文从对外经济贸易大学两代统计学人的视角,回顾了现代中国海关货物贸易统计主流地位演进历程,剖析了中美货物贸易统计差异的原因,澄清了贸易增加值核算的相关表述,并对数字经济背景下海关统计工作的创新进行展望。
