A Natural Resource Scarcity Typology: Theoretical Foundations and Strategic Implications for Supply Chain Management

World population growth and increased consumption stemming from economic leveling are leading to scarcity of a number of natural resources on a global scale. Scarcity of critical natural resources such as oil, water, food, and precious metals has the potential to greatly impact commercial activity as the twenty‐first century progresses. The challenge of continuing to provide needed goods and services in the face of these constraints falls to supply chain managers, who are ultimately responsible for delivering utility to customers. Unfortunately, there has been almost no research focused on supply chain strategies aimed at mitigating natural resource scarcity’s (NRS) potential effects. The current research positions NRS as a supply chain risk and proposes an NRS typology based on key resource attributes. Supply chain mitigation strategies to counter each resource status are offered, with an overall objective of improving supply chain performance. The study recommends future research aimed at further developing theory and methods for countering NRS based on resource, systems and behavioral theories. In addition, this study has critical implications for practitioners faced with the growing threat of NRS in their supply chains.     

Safety at play: let's all help to prevent drowning

The association between place of residence, population density, relief and type of event (collision or non-collision of the vehicle) has not been evaluated in developing countries. The main objective of this study is to determine the differential factors associated with the occurrence of deaths of collision and non-collision automobile users in Patagonia, Argentina. A multiple logistic regression analysis was performed using as the dependent variable death by car accident (collision or non-collision of the vehicle) and sex, age, place of residence of the victim, relief and population density as the independent variables. Collision fatalities were related to areas of high population density, while non-collision fatalities were related to areas of low population density, mountainous landscape and place of residence of the victims outside the Patagonian region. The results obtained in this study indicate the need to develop differential primary prevention policies by place of residence of car occupants, focusing on Patagonia non-resident drivers and by emphasising non-collision accidents.     

江苏应对人口老龄化问题的政策研究报告

对南京、扬州、张家港等地老年人的生存和精神状况进行实地调研，深度剖析江苏人口老龄化问题及其相关政策。江苏城镇养老服务社会化工作已初见成效，但是存在老年社会保障财政压力渐显、老年社会保障差异化加剧、现行老年保障体系呈现“碎片化”状态等问题。针对现存问题，提出完善江苏老年社会保障体系的对策和路径。     

股票回购、现金股利替代性与研发投资——基于迎合渠道的比较分析

传统观点认为,股票回购与现金股利存在替代关系,同时在资金约束以及管理层短视情形下,二者对企业中长期研发投资支出产生负向冲击。而“边分红,边研发”却是目前我国上市公司的普遍现象。基于此背景,利用2014-2017年我国A股上市公司样本数据,在迎合渠道下分析股票回购与现金分红行为对研发投资的影响及差异。研究发现：两种分配行为并非具有完全替代性,虽然二者均会通过迎合渠道对研发投资产生正向影响,但迎合渠道又存在差异。其中,现金股利多通过股权融资渠道发挥作用,而股票回购多通过理性迎合渠道发挥作用。     

退休人口再就业决策的影响因素研究 ——基于中国健康与养老追踪调查数据

夯实财富储备,改善劳动力有效供给是积极应对人口老龄化的重要措施。本文基于中国健康与养老追踪调查数据,全面考察了退休人口再就业的动因,着重分析享受养老待遇和养老待遇水平对退休人口再就业决策的影响。实证结果表明:享受养老待遇对退休人口再就业产生负激励效应;养老待遇水平提高会明显降低退休人口再就业的可能性;个人负债占资产比重越大,退休老年人再就业概率越高;配偶退休、年龄增大、健康状况差会显著降低退休人口再就业概率。对此,本文提出以下建议:适当延迟退休年龄,增加老年人口经济收入;养老保险制度应兼顾保障性和劳动力市场功能;构建老年就业服务体系,保障老年就业权利。

Population Structure and Housing Prices: Evidence from Chinese Provincial Panel Data

This study analyzes the relationship between the proportion of the economically active population aged 15–64 to total population and housing prices. A panel of 31 provinces in China from 2002 to 2014 is used in our analysis. We find empirical evidence that the impact of the population structure on housing-price growth increases as the population growth rates rise. This observation suggests that, to understand provincial housing price movements in China, one should consider the ratio of working-age population to total population in a province. The main policy implication is that Chinese policymakers need to ensure a moderated population growth to effectively promote stability in housing prices and the economy.     

个体差异、企业特征、制度保护与流动人口社会保险可及性——基于“福利三角”理论模型的实证研究

"福利三角"理论是现代社会政策研究的重要范式,其也可运用于经验研究。本文基于"福利三角"理论视角,从个体差异、企业特征、制度保障三个维度,利用南开大学"2013年流动人口管理和服务对策研究问卷调查"数据,对流动人口社会保险可及性及其影响因素进行实证研究。分析发现,在个体特征方面,受教育程度、工作年限等对流动人口人力资本具有关键影响的因素,企业性质、行业类型等企业特征,劳动合同、合同协商、工会等制度保障因素对流动人口社会保险可及性具有显著影响。在此基础上,应提高流动人口社会保险可及性。     

基于多源数据与GIS技术的福建省人口数据网格化

基于多源数据融合思想,以福建省第六次人口普查数据为基础,利用GIS技术,将DMSP/OLS、土地利用、DEM、MODIS等多源数据提取其像元值转入同一位置的网格中,消除多源数据位置不匹配难题,运用聚类——多元逐步回归分析构建了人口网格化模型模拟及精度检验,最后进行空间网格化表达。可为有关部门在灾情速判、区域经济发展调控、资源可持续发展等提供数据支持。     

传统生育文化对我国人口可持续发展的影响

我国的传统生育文化是在传统农业社会的经济和文化背景下产生的,现在仍然有着重要影响.为了实现我国人口的可持续发展,必须重视文化因素,推动旧的生育文化向新型生育文化转变,创造适合人口可持续发展的文化环境.
