Urban environment, spatial fragmentation and social segration in Latin America: Where does innovation lie?

To “review the urban question” in terms of sustainable development, the premise is formulated that improving infrastructures, equipment and services to preserve the natural and built urban environment is costly and generates expenses of all kinds—at economic and social levels. Without the introduction of equalisation mechanisms, these expenses will increase inequalities between different parts of the urban population.As confirmed by 2 Latin American case studies in Buenos Aires, Argentina, and La Paz Bolivia, the quality of urban environment depends directly on improving living conditions for the resident population. The aim is to assist the poor in developing a rubbish disposal service for the families living in the informal settlements of La Paz, or to extend water supply to the poorer areas on the outskirts of Buenos Aires. The collective benefits of these “innovations” are self-evident. However, understanding the environmental issues involved, and evaluating the social impact of these innovations, means examining what motivates their implementation.The first difficulty was in finding financial and economic information on the global cost of the new technologies, due to the lack of managerial culture and the discretional attitude of private enterprises and public administration.A second observation is that the social dimension of the environmental upgrading process in Latin America cities has been neglected by the main urban decision-makers. In all the contexts, the evolution of the projects’ implementation clearly demonstrates that social issues cannot be dissociated from political ones. Although the players themselves often find it difficult to estimate economic costs, these are nonetheless real and represent burdens that should be distributed equitably among the beneficiaries of services; but which are, in practice, often viewed in terms of profit. This leads to conflicts between different population groups, the political authorities and private intermediaries.Rather than viewing technological action as an unique “source” of innovation, we must consider its global dimension via the social practices it generates. On the other hand, we should reposition every specific event in its immediate environment and see how it reflects contemporary macro-social processes, in a world of “globalisation”.

政府研发资助是否有利于撬动跨境投资的技术创新溢出？——基于IFDI与OFDI双向演化的新视角

如何通过政府研发资助撬动跨境投资的技术创新溢出是新时代深化全面开放和创新驱动的关键所在。本文以IFDI和OFDI双向演化视角,揭示了跨境投资技术创新溢出的逻辑关系以及政府研发资助的动态调节机制。以介质影响门槛模型和省级面板数据实证研究发现：IFDI技术创新溢出是一个由强到弱的过程,而OFDI技术创新溢出呈现出先抑后扬的“U”型规律;政府研发资助对双向跨境投资技术创新溢出具有显著而不同的门槛影响,当研发资助强度高于0.2491时,能够撬动IFDI技术创新溢出;研发资助强度高过0.2501时,能够有效释放OFDI技术创新溢出,相较而言对“走出去”的创新驱动更为有力。相应结论在合理的内生性检验和稳健性检验时依然成立。通过进一步研究发现,政府研发资助对双向跨境投资技术创新溢出的调节影响存在一定的空间异质性,特别是在东中西部地区呈现出较为复杂的演化特征。由此为提高政府研发资助效率,双向撬动跨境投资的技术创新溢出红利,提出了动态优化、分区调节的系统策略。
