摘要
本文分析了知识外部性对地区出口生产率的作用，知识外部性可能源于聚集经济和地区知识。知识外部性是知识在经济主体之间传播的结果，其传播范围不仅限于地区边界，而且在不同技术密集度的部门之间存在差异。我们利用葡萄牙 23 个 NUTS III 地区和巴西 137 个中区的出口数据（包括高、中高技术密集度部门和低技术密集度部门的出口数据），发现葡萄牙高、中高技术部门和低技术部门之间的生产率差距大于巴西。利用空间计量经济学技术，我们发现研发对高技术部门和中高技术部门的出口生产率有积极影响，但仅限于葡萄牙的情况。两国的空间溢出效应不同。专业化和多样化经济对葡萄牙高新技术部门的出口生产率有负面影响。在巴西的案例中，据估计，专业化经济对生产率产生了积极的直接和总体影响。
The export productivity of Brazil and Portugal by technological intensity: A spatial comparative analysis
This paper analyses the role of knowledge externalities, which may result from agglomeration economies and regional knowledge, on regional export productivity. Knowledge externalities are the result of knowledge transmission between economic agents, being its dissemination not limited to regional borders and varies between technological intensity sectors. Using a panel of 23 NUTS III Portuguese regions and the 137 Brazilian mesoregions with export data for High and Medium-High technological intensity and Low technological intensity sectors, we found a larger productivity gap between the High and Medium-High Technological sector and the Low Technological sector in Portugal than in Brazil. Using spatial econometric techniques, we found a positive impact of R&D on export productivity in the High and Medium-High Technological sector, but only in the Portuguese case. The spatial spillover effects are different in the two countries. The specialisation and diversifications economies have a negative impact on the export productivity in the Portuguese High and Medium-High Technological sector. In the Brazilian case, it was estimated a positive direct and total effect on productivity due to specialisation economies.
期刊介绍：
Regional Science Policy & Practice (RSPP) is the official policy and practitioner orientated journal of the Regional Science Association International. It is an international journal that publishes high quality papers in applied regional science that explore policy and practice issues in regional and local development. It welcomes papers from a range of academic disciplines and practitioners including planning, public policy, geography, economics and environmental science and related fields. Papers should address the interface between academic debates and policy development and application. RSPP provides an opportunity for academics and policy makers to develop a dialogue to identify and explore many of the challenges facing local and regional economies.
