　　英文摘要：This paper investigates the selection effects of market size on firm productivity by using firm-level data on Chinese manufacturing industries for the period 1998–2007. China's provinces are an appropriate proxy for market size due to local (provincial) protectionism, which creates fragmented domestic markets. The estimated results using a quantile approach show significant selection effects for 15 out of 29 sectors. We find that provinces above the median employment density weed out approximately two to eight percent more firms than those below the median density. Further, the sectors with stronger local protections tend to exhibit greater selection effects. We also find that firm selection effects are robust with respect to alternative productivity estimates, grouping criteria, and spatial units, but can be different across types of firms and may suffer from downward bias due to the noise in productivity estimates and the exclusion of small firms.

　　中文摘要：本文利用1998-2007年中国制造业企业数据，探讨了市场规模对企业生产率的选择效应。由于地方保护主义导致国内市场分散，中国各省是衡量市场规模的合适指标。使用分位数方法的估计结果显示，29个部门中的15个具有显著的选择效应。我们发现，高于就业密度中值的省份比低于就业密度中值的省份淘汰了大约2%至8%的企业。此外，具有更强地方保护的部门往往表现出更大的选择效应。我们还发现，相对于其他生产率估计、分组标准和空间单元，企业选择效应是稳健的，但在不同类型的企业中可能是不同的，并且可能由于生产率估计中的噪音和小型企业的排除而遭受向下偏差。
