上海人口郊区化与产业郊区化协同发展研究

上海市人口郊区化和产业郊区化发展的过程中,由于人口规划和城市基础设施建设、产业发展和城市之间缺少有效地协调机制,公共服务资源配置相对滞后,造成郊区新城人户分离、产城分离问题日益严重。通过对社会、经济、政策等相关因素的分析,鉴于郊区经济发展对人口的导入功能将进一步增强,郊区人口还将持续增加,从人口郊区化与产业郊区化协同发展的角度对产业发展、人才引进、公共资源配置等方面提出了建议。

Enticing the Stork: Can we Evaluate Pro‐Natal Policies Before Having Children?

Aside from immigration, the only meaningful demographic lever available to policymakers attempting to moderate the rate of ageing is the birth rate. This article departs from previous analyses of pro‐natal policies by studying determinants of pro‐natal options ex ante, which represents an advantage for policymakers looking to craft policies with prior knowledge of whether or not a demographic policy will have a significant effect. Our multinomial regression model for a US sample involving college students shows that the preferred choice of pro‐natal incentive is dependent on gender, economic class, number of planned children and migrant status. We find that females are more likely than males to choose any pro‐natal incentive over no incentive. The highest odds for increasing planned number of children are for maternity leave and parental leave options. Respondents associating themselves with the poorest economic class are more likely to choose daycare or government grant as pro‐natal options.     

Retrospect of the Chinese Exchange Rate Regime after Reform： Stylized Facts during the Period from 2005 to 2010

In the present paper, we estimate the de facto RMB exchange rate regime, the currency basket, the floating band and the foreign exchange market pressure before and after the reform of the Chinese exchange rate regime in 2005. We find the following stylized facts： the value of the RAIB became stable after the reform; the weight of the US dollar remained high in the basket, while other currencies remained statistically significant; and the floating band gradually increased to lO percent during 2005-2008, and then greatly narrowed from the late summer of 2008 under the assumption of a yearly resetting interval. We find that the foreign exchange market pressure increased from 2005 to 2008. A possible reason is that the weight of the US dollar in the basket was slightly lower than the share of the US dollar in total transactions on the Chinese foreign exchange market. Therefore, it is reasonable for China to adopt a dollar peg exchange rate regime.     

从非稳态出发探讨影响经济增长的因素——一个基于索洛模型的分析

在大多数模型化的经济增长理论中,首先考察的是经济如何达到长期均衡,然后分析一旦经济偏离了均衡增长将如何运行,是否能够重新收敛于长期均衡点。因此遵循均衡—偏离均衡—均衡的分析思路。而在现实生活中,我们所观察到的多是非充分就业下的非均衡的复杂经济状况。本文试图在索洛增长模型的基础上,在非充分就业环境的假定下探讨经济增长以及与之相关的经济运行问题。并且部分地尝试用其解释我国目前的经济运行情况。     

广州市外来人口的空间分布变动分析

利用第三、四、五次人口普查资料,对广州市外来人口空间分布进行分析。1980年代以来广州市外来人口在数量急剧增长的同时,其空间分布格局也发生了根本变化,即由原来主要集中于中心区转向主要集中于近郊区,并逐渐向远郊区延伸。针对外来人口的空间变化规律,提出了加强城市人口管理和城市规划建设的建议。     

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。     

城市流动人口居留意愿研究——基于上海、苏州等地的调查分析

以上海市普陀区、苏州市流动人口问卷调查数据为依据,采用统计分析方法,对流动人口居留意愿的特点、流动人口居留意愿的影响因素以及户籍制度对流动人口居留意愿的影响进行了研究。经济因素对流动人口的居留意愿并没有显著的影响,社会因素的影响更加显著,其中社会融合因素与居留意愿正相关,家乡联系与居留意愿呈负相关关系;从制度因素来看,户籍制度对流动人口居留意愿有一定的影响,表现在它改变了一部分流动人口的居留意愿。     

我国人口资源环境与经济的可持续发展

为了保持经济又好又快的发展,应该正确处理人口、资源、环境与经济的关系;必须长期坚持计划生育的基本国策,控制人口增长的数量,提高人口的质量,减轻过多的人口对资源和环境的压力;提高自主创新能力,转变经济增长方式,发展循环经济,节能减排,建设资源节约型、环境友好型社会,走新型工业化道路,实现可持续发展战略。     

On the forecasting of the challenging world future scenarios

Logistic and power law methodologies for both retrospective and prospective analyses of extended time series describing evolutionary growth processes, in environments with finite resources, are confronted. While power laws may eventually apply only to the early stages of said growth process, the Allee logistic model seems applicable over the entire span of a long range process. On applying the Allee logistic model to both the world population and the world gross domestic product time series, from 1 to 2008 AD, a projection was obtained that along the next few decades the world should experience a new economic boom phase with the world GDP peaking around the year 2020 and proceeding from then on towards a saturation value of about 142 trillion international dollars, while the world population should reach 8.9 billion people by 2050. These results were then used to forecast the behavior of the supply and consumption of energy and food, two of the main commodities that drive the world system. Our findings suggest that unless the currently prevailing focus on economic growth is changed into that of sustainable prosperity, human society may run into a period of serious economical and social struggles with unpredictable political consequences.
