This paper explores the entanglement of ideology and materiality in the production of the spaces of 21st century socialism. “Millennium Cities” are currently being constructed for indigenous communities throughout the Ecuadorian Amazon, with revenues derived from petroleum extracted within their territories. As iconic spatial symbols of the “Citizens’ Revolution”, the Millennium Cities would appear to embody “the original accumulation of 21st century socialism”—a utopian state ideology promising the collective appropriation of natural resources without the dispossession of the peasantry. Drawing on extensive field research, we argue that they are better understood as a simulation of urban modernity that is symptomatic of the predominance of ground rent in South American capitalism, and which conceals the violent repression of an autonomous indigenous project of petroleum‐based modernization. The original accumulation of 21st century socialism can therefore be interpreted as a “fantasy of origins”, which functions to reproduce the primitive accumulation of capital. 相似文献

Since the collapse of the communist system, regional inequalities have increased in Central European Countries. This paper describes an assessment of the impacts of regional development programmes on the development of Hungarian regions at a highly disaggregated level between 2002 and 2008. We construct a multi-dimensional composite indicator to estimate the overall development of rural regions and capture social, economic and environmental dimensions. The impacts of rural development programmes were investigated through counterfactual analysis in combination with Propensity Score Matching and Difference-in-Differences approaches. There has been considerable variation with increasing concentration in the level of subsidies distributed during the analysed period. From a policy perspective, the results are disappointing. Irrespective of the subsidy measures or methodology employed, the impact of the former is very close to zero or non-significant. Our findings cast serious doubt on the effectiveness of development policy and the long-run convergence of European regions. 相似文献

ABSTRACTThis article explores corporate regional engagement and related social capital in non-core regions. Corporate regional engagement comprises various activities of firms to influence regional contexts, which are challenging in non-core regions (e.g. on account of their organizational or institutional thinness). Corporate regional engagement engenders positive effects for regional development when firms collaborate among themselves (bonding social capital) and with other actors (bridging social capital) to improve regional endowments. We assume that dynamic regions have at their disposal higher levels of inclusive social capital in terms of collaboration networks for regional concerns and trust, while less dynamic regions have more exclusive and fragmented social capital. Consequently, less dynamic regions in particular appear to have potential to develop in a more social sense by activating the endogenous potential of region-wide collaboration. Those assumptions are tested based on a survey with Chief Executive Officers from the manufacturing industry from three dynamic and three less dynamic Swiss regions. The findings show that in dynamic regions, more firms are members of regional cross-industry associations, favouring regional collaboration; in less dynamic regions, meanwhile, more firms are members of industry-specific associations and service clubs, where benefits seem to be higher for individual firms than for the regional business environment. 相似文献
