The 1990s in Brazil were a time of institutional advances in the areas of housing and urban rights following the signing of the new constitution in 1988 that incorporated the principles of the social function of cities and property, recognition of the right to ownership of informal urban squatters and the direct participation of citizens in urban policy decision processes. These propositions are the pillars of the urban reform agenda which, since the creation of the Ministry of Cities by the Lula government, has come under the federal executive branch. This article evaluates the limitations and opportunities involved in implementing this agenda on the basis of two policies proposed by the ministry — the National Cities Council and the campaign for Participatory Master Plans — focusing the analysis on government organization in the area of urban development in its relationship with the political system and the characteristics of Brazilian democracy.  相似文献

"拆迁上访"警示城市化过热   总被引:2,自引:0,他引:2  
本文认为,造成"拆迁上访"的深层原因是城市化过热,让拆迁户背负了城市化的成本.城市化的实质是投资活动,应遵循投资的一般规则.要解决城市化过热的问题,需要政府把城市化当成社会化的市场化的投资活动,转换自己在城市化中的角色与职能,宏观调控微观放手,并在城市化中自觉接受民主监督与法律约束.  相似文献

Political entrepreneurship occurs when an individual acts on a political profit opportunity. These profit opportunities can be divided into two categories: productive, and predatory. Productive opportunities enable entrepreneurs to profit from enhancing the efficiency of government, while predatory opportunities enable entrepreneurs to profit from forcibly transferring resources from some to others. This analysis shows that political institutions tend to favor predatory over productive political entrepreneurship, and shows that what is sometimes referred to as political exchange does not have the same efficiency characteristics as voluntary exchange in private markets.  相似文献

In this paper, a survey of more than 1600 firms in the five largest city regions of Norway is described in order to examine how a firm's innovative capacity is affected by three types of factors: factors related to the manager, the structure of the firm and the broader geographical location. By combining perspectives from the fields of management and economic geography in a logistic regression analysis, we find that the two key drivers of firm-level innovation in Norway are the presence of open-minded managers and evidence of collaboration with international partners. Moreover, these two factors are mutually reinforcing, as firms with open-minded managers also tend to engage more with international partners and vice versa.  相似文献

The managerial competencies required by professionals in the construction industry in Tanzania to operate effectively in a business environment which is changing as a result of a transition from a socialist to a free-enterprise economy, economic liberalization, globalization and regionalization are explored through a qualitative study. The study reveals that local Tanzanian construction firms are finding it difficult to compete with foreign companies for projects. This is mainly because Tanzanian professionals lack the competencies required to compete and manage projects in a liberalized market economy.

The study thus highlights the need for Tanzanian construction professionals to acquire a better grasp of both occupational and organizational competencies. In this respect, it is suggested that they need post-experience training in order to acquire the competencies required to function successfully in a commercial environment.  相似文献

This article explores and theorizes the ways in which urban space and political contestations are mapped onto each other. The ethnography illustrates the multifaceted transformations in a notoriously secularist neighborhood of ?stanbul, Te?vikiye, as it first turns into a high‐consumption locality in the post‐1980s, then into a high‐conflict urban space in the new millennium on the arrival of Muslim high‐spenders, particularly headscarved women. Aiming to fill the gap left by the absence of spatial analysis from political science and political sociology, I argue that the urban neighborhood becomes central for political contestation when both government and opposition fail to protect and secure liberties and rights. Now that devout Muslims are integrated into highly contested urban sites and share bourgeois lifestyles, ordinary people act in defense of their ‘sphere’ of freedom and privacy. This new territoriality is largely symptomatic of increasing fears of losing freedom, privacy and social status. This spatial defensiveness is reinforced by people's decreasing trust in, and increasing demands from, the state for the protection and security of their rights and liberties. My overarching argument is that exclusive attention to the bipolar clash between devout Muslims and secularists under the rubric of ‘neighborhood wars’ obscures multipolar conflicts around the discontents stemming from authoritarianism and democratization.  相似文献

Environmental sustainability is a growing global concern. Environmental management systems (EMS) could be an effective strategic tool to help firms deal with their sustainable development. However, whether EMS certification pays off financially and how it takes effect can be debated. Thus far, these questions remain largely under‐researched. In particular, the effects of EMS certification on financial performance are inconclusive, and the reasons explaining the effects are underdeveloped. This study aims to enrich the current research by exploring the mediating and moderating roles from the perspective of cost‐efficiency trade‐offs to reveal how EMS certification affects financial performance. Applying a PROCESS procedure analysis and causal mediation analysis to a sample of 1,751 Chinese listed manufacturing firms from 2008 to 2016, this study shows that the effect of EMS certification on firms' financial performance is insignificant because their operating costs burden increases while their marketing efficiency and managerial efficiency improve. For the first time, this study demonstrates the moderating role of industry peer learning, as the mediating effects decrease with the growth of industry peer learning.  相似文献

Despite the widespread recognition of the paybacks of “going green” and “going clean,” limited research has focused on the impact of lean‐green strategy on firm growth. In this study, we contribute to strategy and environmental sustainability literatures by investigating the possibility that the influence on lean‐green strategy and firm growth is driven by different levels of industry competition, managerial power, and family ties. Using panel data from 732 firms in four major industrialized economies (the United States, Germany, France, and the United Kingdom), we found that lean‐green strategy positively relates to firm growth and this relationship is amplified at higher levels of competition, managerial power, and family ties. Theoretical and practical implications of the study are also discussed.  相似文献

为了进一步提高项目价值,项目经理必须认识项目规划和管理的不确定性。传统的工程项目规划、预算和管理往往认为不确定性降低了项目的价值,并没有从中充分地挖掘增加项目价值的机会。实物期权方法就是利用战略灵活性来识别和把握在动态不确定中所隐蔽的项目价值。通过一个高速公路项目的案例来展示实物期权方法所带来的管理灵活性对评价和选择战略的重要意义。还讨论了实物期权应用中的一些问题,指出了今后研究的方向。  相似文献

The paper explores the contributions of Joseph Schumpeter and Albert Hirschman to our understanding of the dynamics of modern democratic capitalist economies and suggests that much of their respective work displays intellectual overlap and complementarity. It is primarily focused upon the role of economic and political processes as forces of change and adjustment and the necessary degree of built-in inertia required to permit orderly rather than chaotic responses.  相似文献
