Spillovers and the growth of local industries
研究了意大利制造业部门间产业间动态关联的方向与性质，发现多样性对增长重要但各行业需特定多样性，且溢出多发生在投入产出关系中，常从下游传导至上游。
In this paper we investigate the nature and directions of inter‐industry dynamic linkages across Italian manufacturing sectors. We perform a very disaggregated analysis in order to identify, for each 3‐digit industry, which composition of industrial activity is more conducive to growth. We find that diversity matters for growth, but each industry needs its own diversity. We provide some evidence of clustering of industries based on dynamic externalities. We find that many spillovers occur within input‐output relationships. They often originate in downstream sectors favouring the growth of upstream industries. Lastly, the importance of spillovers does not depend on the technological intensity of the industry.
