主 题：Quantifying the Aggregate Effects of Inter-Firm Knowledge Networks
主讲人：王子 上海财经大学助理教授
主持人：邵翔 博士
Abstract: This paper evaluates the impacts of inter-firm knowledge networks on aggregate growth and welfare. We use data on patent citations across Chinese manufacturing firms to study the structure of inter-firm knowledge networks. We document that within a narrowly-defined industry firms still occupy heterogeneous positions in patent citation networks, and that a firm tends to grow faster if it cites patents from faster growing firms.
These empirical regularities motivate and guide the development of a quantifiable general equilibrium model with firm innovation and inter-firm knowledge diffusion. Using data on patent citations, we estimate the model’s key parameters via a constrained simulated method of moments and assess its fit to the data. Simulations of our model are used to study (1) how firm-level instantaneous shocks propagate via inter-firm knowledge networks and translate into aggregate dynamic effects, (2)how governments should subsidize firm innovation in the presence of inter-firm knowledge spillovers, and (3) how inter-firm knowledge networks affect the productivity and welfare effects of trade liberalization.
