想问一下，在市场营销或经济领域中“hit-and-run”该怎么翻译？

最近在翻译一篇外文文献，里面有“hit-and-run”我不懂是什么意思，还请大神帮助。

例句是：1.Deregulation allows any American carrier to serve any airport pair creating the potential for ‘hit- and-run’ entry, limiting monopoly market power .

2.The defense against this in the deregulated American domestic aviation industry is from low barriers to entry permitting ‘hit-and-run’ competition
