Abstract ：

本书使用 2011-2012 年中国健康与养老调查（CHARLS）全国基线数据，分析生命历程中的主要事件包括结婚、生育、丧偶、再婚、工作等事件与中老年期健康之间的关系。本书研究了夫妻年龄匹配模式、教育匹配模式与中老年期健康的关系，发现男小女大的年龄匹配模式， 中老年期健康状况差；研究了女性生育与中老年期健康之间的关系，发现多育、 早育对中老年期健康不利， 教育程度和个人收入水平中介了早育与中老年期女性健康之间的关系；测算了老年人口的丧偶指标，发现夫妻年龄差对丧偶指标有较大影响；究了丧偶后再婚与中老年期健康之间的关系， 发现丧偶后再婚对中老年期心理健康的“保护效应” 强于对生理健康的“保护效应”。发现曾经在体制内工作的老年人的健康存在“体制庇护”。

Abstract ：

There is a growing recognition that optimizing urban form can reduce road transport-related carbon emissions, particularly in carbon emissions by daily travel. In this study, we proposed an improved bottom-up approach combining Vehicle Specific Power (VSP) model and Enhanced Two-Step Floating Catchment Area (E2SFCA) method to estimate the carbon emissions by daily travel. Then, a geographical weighted regression (GWR) model considering the urban residential density (RD) and land use mix level (LML) of urban form as independent variables was employed to explore the relationship between urban form and carbon emissions. A typical working day (June 5th of 2017) of Hangzhou was chosen as a case study in this paper. The results showed that (1) per hour carbon emission in the morning peak period of 6:30 a.m.-9:30 a.m. was higher than that in the evening peak of 22:00–24:00 by 33.34%; and distribution of the highest carbon emissions was in the eastern, northeastern and northwestern parts of Hangzhou; (2) The RD and LML were positively and negatively associated with carbon emissions. and the coefficients for Ln (RD) and (LML) ranged from 0.29 to 0.70 and from −9.01 to −6.06, respectively. (3) The spatial distribution of coefficients demonstrated that the highest effects of RD on carbon emissions were observed in the central parts of Hangzhou, and those of LML on carbon emissions were observed in southern Hangzhou featured by industrial parks. This study may provide insights to mitigate carbon emissions from daily travel with multiple public policies including mixed land-use policies, urban density control and spatial planning. © 2020 Elsevier Ltd

Abstract ：

In recent years China has promulgated a large number of real estate regulation policies to ensure the stability of the real estate market, prevent financial risks, balance the supply and demand and promote social security. But whether from the perspective of the efficiency of public policy or the effectiveness of public policy, It can be found that there are policy failures in China's real estate market. The emergence of policy failures is not only due to the behaviour of the government, developers and the public, but also due to the inner problems and shortcomings of China's real estate regulation policies. On the basis of the study of the China's real estate regulation policy's failure, this paper analyzes the four main problems existing in current China's real estate regulation policies, and puts forward some countermeasures and suggestions to improve China's real estate regulation policies. © Advancement of Construction Management and Real Estate, CRIOCM 2017.All right reserved.

Abstract ：

With rapid urbanization in China, there is an urgent need to better understand spatial patterns of cities’ carbon transitions in urban metabolism processes and to explore ways to achieve low carbon cities through sustainable urban planning. In this study, we took Hangzhou City as an example, and firstly analyzed changes in carbon emission and sequestration based on land use types, using data with 5 years interval from 1995 to 2015. We then quantified both harmful and beneficial carbon transitions by land use changes spatially. Harmful carbon transitions are processes that cause carbon sequestration decreases or carbon emission increases and the beneficial ones are the opposite processes. Finally, we employed a panel data regression analysis to investigate how urban forms and road structures influence urban carbon emission at the district level. We found that carbon emissions experienced a nearly five times increase, while carbon sequestration decreased by 22.29%. And the land use change from cultivated land to industrial land accounted for 61.05% of the harmful carbon transitions. In addition, the spatial analysis of urban carbon transitions indicated harmful carbon transitions always sourced from the eastern parts of Hangzhou. Most beneficial carbon transitions were located in the urban central area and western mountainous areas. The panel data analysis demonstrated that urban expansion modes with high connectedness and a better coupling relationship between urban form and road structure could help to emission reduction, and a mononuclear urban expansion mode at the district-level exerted a positive influence in relation to carbon emissions increase. This study provided an approach to assess urban carbon metabolism and help to better understanding of low-carbon urban form. © 2018 Elsevier Ltd
