低碳生态城市视阈下的环境保护问责制构建

伴随着全球碳排放量的迅速上升，低碳生态城市建设模式势在必行。分析低碳生态城市的基本内涵及建设低碳生态城市的可能性和必然性，为政府在城市管理方面提供了新的思路。要通过制度创新，完善责任监督体系，加强考核和建立惩奖机制，以善治理念为指导来建立和完善我国的环境保护问责制，营造绿色、高效、和谐、健康、可持续发展的城市。     

Research of China＇s Development Dilemma and Countermeasure of CDM Project in ＂Post-- Kyoto Era＂

＂后京都时代＂我国CDM市场可谓机遇与挑战并存。主要存在项目类型分布不合理、最终签发成功率低、融资渠道单一、缺乏科学合理的碳贸易体系等问题,因此政府相关部门应推出鼓励政策引导CDM项目协调发展;培育咨询机构、提高项目申报通过率;加快我国＂碳金融＂建设与改革,为CDM项目提供更多融资渠道选择;构建科学合理的碳贸易体系,以促进我国节能减排工作和CDM市场科学、健康、持续发展。     

Comment on Bruce J. Katz and Margery Austin Turner's “Who should run the housing voucher program? A reform proposal”

Abstract

There is much evidence that the housing voucher program has successfully met its two main goals: housing low‐income families and expanding housing opportunity. Nonetheless, efforts to address the program's limitations could improve success. We agree with Basgal and Villarreal that, on the subject of housing mobility, the focus of Katz and Turner is misplaced.

In addition to proposing a solution that does not address the problem, Katz and Turner fail to consider three key points: First, there is no consensus or clear definition of what “mobility” means, how it is measured, and what standard we hope to achieve. Second, the role and impact of family choice in the locational outcomes of voucher holders is a major factor. And third, the considerable trade‐offs in outcomes that result from a greater emphasis on mobility should be examined.     

Housing vouchers in the United States,great Britain,and the Netherlands: Current issues and future perspectives

Abstract

We compare the current U.S. housing voucher program with the British housing benefit and the Dutch housing allowance programs. After presenting the theory behind income‐related housing support, which underpins both the U.S. and European systems, we compare the three programs with respect to their scope (the budgeted versus the entitlement approach), the relationship between housing support and rent levels, the poverty trap, moral hazards, and administrative problems.

The United States can learn from Great Britain and the Netherlands that a full entitlement program can best promote equity, but given the present political and economic climate, it is unlikely that Congress will adopt such a program anytime soon. Great Britain and the Netherlands can learn from the United States how to design a more efficient tenant subsidy program, one that provides incentives to find less expensive units and promotes family self‐sufficiency through enhanced job‐seeking behavior.     

Affordable housing in New Urbanist Communities: A survey of developers

Abstract

Despite the unequivocal goal of income diversity as expressed in the Charter of the Congress for the New Urbanism, one of the more significant challenges facing the movement has been the creation of socially diverse neighborhoods, especially ones that include a mix of incomes. Although recent reports show that most New Urbanist developments are being built for upper‐middle‐class residents, some projects have managed to support income diversity. This article takes a closer look at those projects, reporting on the results of a nationwide survey of New Urbanist developers.

We found that many developers have used complex, creative schemes to make affordable housing possible within the New Urbanist context. Developers created affordable opportunities by combining available government programs, partnerships with nonprofits, and innovative design solutions. These efforts have provided important sources of affordable housing within the context of walkable communities—serving as examples that should be emulated by future developers.     

Beyond Worst Case Needs: Measuring the Breadth and Severity of Housing Insecurity Among Urban Renters

ABSTRACT

Many indicators of renter household insecurity remain widespread or have shown signs of worsening in the past decade, including unaffordability, poor unit conditions, overcrowding, and evictions. Most research to date has examined each of these conditions as a standalone problem, without examining the extent and severity of simultaneously occurring housing problems. This study closes that gap by examining the suitability of measuring housing insecurity as an index of multiple variables within four identified dimensions: unaffordability, poor conditions, overcrowding, and forced moves. Results show that dimensions of housing insecurity are highly correlated and suitable for measurement as an index. The proposed index shows that housing insecurity is widespread among U.S. renters, but varies greatly in severity and type.     

To move or not to move: Relationships to place and relocation choices in HOPE VI

This article has two purposes. First, it explores the ideas of vulnerability, precariousness, and resilience as they apply to people, housing, neighborhoods, and metropolitan areas. People might be more vulnerable to shocks or strains, we propose, if they are members of racial/ethnic minorities, recent immigrants, non-high school graduates, are children or over 75 years old, disabled, recent veterans, living in poverty, or living in single-parent households. Housing may be more precarious, we propose, when it is rented, multi-family, manufactured, crowded, or subject to overpayment. The article goes on to document the relationships between potential personal or household vulnerability and potentially precarious housing conditions. Microdata from the 2005–2007 American Community Survey suggest that an important minority of people have multiple vulnerabilities; these vulnerabilities associate with residence in precarious housing. We suggest that policy be directed toward precarious situations most likely to afflict the most vulnerable populations, especially single-parent households and immigrants.     

Comment on Langley C. Keyes et al.’s “Networks and nonprofits: Opportunities and challenges in an era of federal devolution”

Abstract

Housing markets are determined by a complex interplay of consumers and suppliers. The Keyes et al. article discusses the changing landscape for nonprofit housing providers and what recent developments in federal housing assistance policy will mean to them. But this perspective is too narrow to predict the effects of changes in federal housing policy because all housing providers are somewhat interrelated. All housing providers need to be considered, and using the terms “for‐profit” and “nonprofit” to distinguish between the two types of providers is unfortunate and misleading.

For‐profits and nonprofits are fundamentally different: They place a different emphasis on community, and nonprofits can often deliver subsidies that for‐profits cannot. In addition, the strengths and the skills needed to produce housing under somewhat different objectives have led to some specialization. Ultimately, however, determining the optimal provider or mix of providers is best left to local and state governments as federal housing assistance devolves.     

Creating an enabling environment for housing: Recent reforms in Mexico

Abstract

A recent World Bank policy statement on housing advocates the reform of government policies, institutions, and regulations to enable housing markets to work more efficiently. The policy statement identifies several instruments that governments can use to address housing market constraints, and to improve the performance of the housing sector as a whole, while paying particular attention to the needs of the poor.

In recent years, the government of Mexico has employed many of the enabling instruments described in the World Bank's housing policy statement. This article reviews the role of housing in the Mexican economy and the major reforms that the Mexican government has implemented to improve the operation of the housing market so that private lenders and home builders can play an expanded role in addressing the country's housing needs. The World Bank has supported the government's reform program, and since 1985 it has lent more than $1.2 billion to Mexico for low‐income housing projects.
