The implications of heterogeneous resource intensities on technical change and growth
分析了部门间自然资源使用强度差异如何使技术变革偏向资源密集型部门，并探讨了资源税、研发补贴和公共品供给对长期增长和结构政策的影响。
Abstract We analyze the long‐term dynamics of an economy in which sectors are heterogeneous with respect to the intensity of natural resource use. It is shown that heterogeneity induces technical change to be biased towards resource‐intensive sectors. Along the balanced growth path, the sectoral structure of the economy is constant as the higher resource dependency in resource‐intensive sectors is compensated by enhanced research activities. Resource taxes have no impact on dynamics except when the tax rate varies over time. Research subsidies and the sectoral provision of productivity‐enhancing public goods raise growth and provide an effective tool for structural policy.
