城市流动人口权益保障与犯罪预防探讨

我国改革开放以来，人口流动成为普遍的社会现象，以农民工为主的城市流动人口的急剧增加，带来一些新的社会现象，主要是流动人口的合法权益得不到保障和流动人口违法犯罪现象增多。城市流动人口的“犯罪率增高”与“权益得不到保障”是紧密相关的，应制定一部统筹性的、高效力的法律，保障我国城市流动人口合法权益，并预防流动人口违法犯罪。     

The determinants of efficiency: the case of the Spanish industry

The aim of this paper is to analyse the factors explaining the technical efficiency of Spanish industrial sectors during the period 1991–1994 using the Survey of Business Strategies (SBE) of the Ministry of Industry and Energy. It analyses whether efficiency can be explained by factors external to the firm such as the degree of competition in the markets in which it operates, characteristics of the firm (size, organization, advantages of location, participation of public capital, etc.), as well as the effects of dynamic disturbances that may affect the degree of utilization of the productive capacity.

中国人口老龄化与居民储蓄之间关系的实证分析——基于1979年—2007年的数据

文章使用1979年—2007年中国居民人均储蓄、人均GDP、人口老少比和实际利率的数据,利用向量自回归模型（VAR）,分析了人口老龄化对居民人均储蓄的影响效应,分析结果显示,在中国处于人口老龄化的初期阶段,中国居民的高储蓄是应对人口老龄化的理性选择。随着人口老龄化趋势的快速发展,中国将快速进入中度老龄化阶段,伴随着劳动力数量和比例的下降,居民人均储蓄将会呈现下降趋势。     

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。     

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.
