Catch-Up Growth and Inter-industry Productivity Spillovers: Evidence from Trade Data
利用四十年贸易数据，估计了行业间生产率溢出对发展中国家出口导向型增长的重要性，发现溢出效应在技能密集型行业更大，且初始制造业比较优势对追赶增长至关重要。
Abstract Where and when does export-led growth work? This paper estimates the importance of inter-industry productivity spillovers for the export-led growth of developing countries. My empirical strategy is based on a standard quantitative trade model that features sector-level gravity in trade flows. Applying the framework to four decades of trade data, I find clear evidence of spillovers, which are larger for skill-intensive sectors. The estimates imply that patterns of sectoral specialization play a quantitatively important role in accounting for the slow convergence of labor productivity in tradable sectors. Quantitative exercises suggest that export-led growth works for poorer countries with an initial comparative advantage in manufacturing, as these countries can use foreign demand from richer countries to reallocate labor towards sectors with high spillovers.
