中文摘要

我们考察中国一项将更多城市用地配额分配给欠发达地区以缩小区域差距的土地政策。实证上,该政策使东部地区相对于内地的生产率下降。一个包含迁移、用地配额约束与集聚效应的空间均衡模型表明,该政策扭曲了区域间的劳动与生产配置,造成可观的产出损失。尽管区域差距有所缩小,但来自欠发达地区的劳动者迁移更少、收入更低。若无该政策,2010年全国产出将高出1.8%,欠发达地区劳动者的收入将高出1.6%。区域转移支付为缩小不平等提供了扭曲更小的替代方案。

Abstract

ABSTRACT We investigate a land policy in China that allocated more urban land quotas to underdeveloped regions to reduce regional gaps. Empirically, the policy decreased productivity in eastern areas relative to the inland. A spatial equilibrium model with migration, land quota constraints, and agglomeration shows the policy distorts labor and production across regions, causing substantial output losses. Though regional gaps narrowed, workers from underdeveloped areas migrated less and earned less. Without the policy, national output would have been 1.8% higher, and workers in underdeveloped areas would have earned 1.6% more in 2010. Regional transfers offer a less distortionary alternative for reducing inequality.
