市场进入成本 市场规模 生产率悖论
市場進入成本 市場規模 生產率悖論
시장진입성본 시장규모 생산솔패론
market entry cost;market size; productivity paradox
文章基于Melitz（2003）的经典模型，分析了进入成本和市场规模对异质性企业市场进入决策的影响。研究表明，当两国完全对称时，高生产率企业同时进入国内国外市场，而低生产率企业仅进入国内市场；当本国市场规模较小、进入成本较高时，只有高生产率企业进入国内市场，低生产率企业则被迫放弃国内市场而选择出口，出口企业的生产率低于内销企业。在考虑了市场规模和进入成本的非对称性后，生产率“悖论”得到了解释。
文章基于Melitz（2003）的經典模型，分析瞭進入成本和市場規模對異質性企業市場進入決策的影響。研究錶明，噹兩國完全對稱時，高生產率企業同時進入國內國外市場，而低生產率企業僅進入國內市場；噹本國市場規模較小、進入成本較高時，隻有高生產率企業進入國內市場，低生產率企業則被迫放棄國內市場而選擇齣口，齣口企業的生產率低于內銷企業。在攷慮瞭市場規模和進入成本的非對稱性後，生產率“悖論”得到瞭解釋。

Based on Melitz＇s classical model raised in 2003, this paper analyzes the effects of entry costs and market size on the entry decision-mak- ing o{ heterogeneous firms. It shows that in two completely symmetric coun- tries, firms with high productivity simultaneously enter into domestic and foreign markets and the ones with low productivity only enter into domestic market; in a host country with small market size and high entry costs, only the firms with high productivity enter into domestic market and the firms with low productivity are forced to abandon domestic market and export their products~ the productivity of exporters is lower than firms with domes- tic sales. After taking account of the asymmetry of market size and entry costs, it provides an explanation of productivity paradox.
