The Impact of Privatization and Competition in the Telecommunications Sector around the World
利用1990-2001年跨国面板数据，发现完全私有化（私人拥有控制权）显著改善劳动和资本配置、扩大服务产出和网络渗透、提高生产率；部分私有化无显著影响；竞争压力通过增加要素投入和全要素生产率促进增长；私有化与竞争在深化网络渗透和抑制服务定价方面存在互补性。
Using a comprehensive country‐level panel data set covering the period from 1990 to 2001, we investigate the impact of privatization and competition in the telecommunications sector around the world. Full privatization, which gave private owners control rights, contributed substantially to improving the allocation of labor and capital, expanding service output and network penetration, and improving labor and total factor productivities. But partial privatization, in which the state retained control rights, showed no significant impact. The increase in competitive pressure contributed substantially to growth in the sector by raising both factor inputs and total factor productivity. We also found evidence of complementarity between privatization and competition in deepening network penetration and in restraining the rise of service pricing among privatized operators. Our results are robust to plausible alternative specifications.
