基于交流外部性的行为主体城市聚集空间结构分析

因行为人寻求空间上交流的需求形成一种聚集的向心力,从而产生在一定区域内其分布状态表现出了单峰分布现状。但是在处于社会中的行为人是以城市为中心进行分布,使行为人聚集的空间结构产生了不同程度的变化。文章综述了行为主体（个人和企业）在交流情况下产生聚集的国内外研究现状,探讨了个人之间聚集社会外部性产生的前提条件,通过数学模型分析个人聚集得出了个人聚集分布的最优结论;通过对企业交流情况下聚集形成中央商务区的均衡分布状况,得出了企业在中央商务区为钟型分布,并且利用信息的传播界限可解释中央商务区的形成的结论,同时也说明了在信息传递条件下写字楼的高度随着距中央商务区距离远近而发生变化的结果。     

中国工业劳动生产率分解及其对地区收入差距的影响研究

用非参数生产前沿方法将我国1978-2007年工业劳动生产率增长分解为效率变化、技术变化、物质资本和人力资本变化的贡献四个部分,并用方差分解方法估算了各部分对地区工业劳动生产率增长差异的贡献,然后采用核密度分布方法分析了上述四个部分对工业劳动生产率差距以及三次产业对地区收入差距的影响。研究发现:(1)物质资本积累是我国工业劳动生产率增长和地区差距的主要来源,人力资本积累的贡献较小;(2)效率虽然对工业劳动生产率增长的贡献较小,但却是工业劳动生产率地区差异的重要原因;(3)技术是要素非中性的,且技术进步主要发生在有效劳均资本较高的地区。(4)1978-1992年期间,地区收入差距主要来自农业劳动生产率增长差异,而在1992-2007年期间,地区收入差距则主要来自工业劳动生产率增长差异。     

中国家庭债务和资产积累关系的实证分析:1997-2008

笔者运用1997年～2008年中国家庭债务和家庭资产积累的时间序列数据,定量分析了家庭负债和家庭资产积累的关系。研究发现,家庭债务和家庭资产积累存在同向的长期均衡关系,家庭债务的变动会影响家庭资产的积累。笔者提出促进家庭资产合理配置和防范中国家庭债务快速增长带来的消极后果的相关建议,旨在为决策部门制定合理的经济政策提供参考。     

Post-Earthquake Land Appropriations and the Dispossession of Rural Women in Haiti

ABSTRACT

This study examines the trajectory of rural women’s labor in the wake of post-earthquake land appropriations in Haiti. Drawing on ethnographic field research conducted between 2010 and 2013, it explores gendered access to land in Haiti in both historical and contemporary contexts, paying attention to the nature of rural gender relations and how they influence women’s access to land and their roles in petty commerce. The study describes the stratification of rural market women, their lived experience, and how losing land access will affect their traditional roles as market women. Ultimately it argues that without access to land, and a paucity of available wage work, recent dispossession will intensify existing vulnerabilities for rural women and narrow their means of household production by forcing them to depend on informal market activity in their roles as machann (market women).     

The Power Underpinnings,and Some Distributional Consequences,of Trade and Investment Liberalisation in Canada

Criticism of trade and investment liberalisation (TAIL) in North America has drawn attention to weak economic performance, wage-profit redistribution, social dumping and fiscal pressure on government programmes as evidence that the TAIL regime has failed to deliver on some of its key promises. This criticism has been unable, however, to establish satisfactory conceptual and empirical connections between the dramatic distributional changes witnessed in the TAIL era and the institutional reorganisation of power that the TAIL regime entrenched. This article will undertake a quantitative assessment of the Canadian political economy to see who the main beneficiaries of the TAIL era have been, contrasting returns to labour and to capital in the pre-TAIL and TAIL eras. Employing tools from the capital as power framework, two pictures are painted: the first picture examines broad changes in the distribution of income and the second examines differential business performance. The evidence from this inquiry suggests that although the official purpose of TAIL was to enhance the prosperity of all Canadians, this trade deal actually represented – both in its intentions and consequences – a political-economic transformation written by dominant capital for dominant capital.     

On the Persistence of Labour Market Insecurity and Slow Growth in the US: Reckoning with the Waltonist Growth Regime

In this article I systematically incorporate empirical work on rising income inequality and wage stagnation into a regulation theoretic framework for analysing macroeconomic growth. The rise of job polarisation and income inequality coincides with a long period of macroeconomic stagnation, both continuing through to the present (with the exception of a brief period of strong growth and declining inequality in the second half of the 1990s). The corporate scramble to restore profit rates after the crisis of Fordism has transformed the institutional configuration of the political economy. In particular, institutions supporting upward mobility and middle-class incomes in the economy have been eroded by the twin forces of internationalisation (leading to the re-emergence of wage-based competition) and employment externalisation (outsourcing, downsizing, antiunionism, etc). The current growth regime, which may be characterised as Waltonist, based on the Wal-Mart model of buyer-driven global supply chains focused on cutthroat wage-based competition and deunionisation, is not transitional but rather embedded in apparently long-term institutional settlements that amount to a dysfunctional regime.     

Vanity and the love of system in Theory of Moral Sentiments

Abstract

Some recent writing on Adam Smith's Theory of Moral Sentiments has emphasised the importance of vanity as one of the most important human motivations. This reading leads to a new version of Das Adam Smith Problem, but this is unwarranted. Such a reading tends to conceal the significance that Smith gave to the love of system, which motivates the actions of the philosopher, the man of state, and above all the entrepreneur. This paper shows, by contrast, that by using this conception we can relate Theory of Moral Sentiments to Wealth of Nations, and reject the idea that these works are based upon contradictory assumptions.     

不同水稻品种对钒的积累及化学形态

通过盆栽试验,研究了钒（V）胁迫下不同品种水稻植株中钒的积累和化学形态。结果表明,不同品种水稻各器官中V的分布为根＞茎＞叶＞子实,两种水稻品种吸收的V主要富集在根部。水稻生长期新优188水稻各器官中V的浓度均低于十优838水稻,如在V处理浓度为100 mg·kg-1时,在分蘖期、扬花期、灌浆期和成熟期,新优188水稻植株根中V含量分别为73.10、92.56、57.46、57.81 μg·g-1,茎叶中为8.79、4.52、2.13、2.56 μg·g-1;十优838水稻植株根中的V含量为59.14、94.93、88.59、89.70 μg·g-1,茎叶中为4.64、3.66、2.29、3.24 μg·g-1。推断十优838水稻较新优188水稻有较强的V吸收能力。两种水稻品种中,根部V主要以活性较低的盐酸提取态（FHCl）和醋酸提取态（FHAc）为主,茎和叶中V主要以盐酸提取态（FHCl）和水提取态（Fw）为主,认为V在水稻根部多以难溶于水的重金属磷酸盐或草酸盐而被固定,限制了水稻中V转移到茎和叶,从而避免了高浓度V对植物光合作用及其他生理过程的干扰。
