在一个内生增长与产品质量改善的模型中，我通过假设创新是非剧烈的，并且当前的领导者在下一次专利竞赛中具有移动优势，对领导力的持续性提供了一个新的解释。在这种情况下，领先者的价值超过了暂时的垄断利润，因为领先者在下一次专利竞赛中获得了额外的利润，尽管外人可以自由进入。这将增加创新的动力，从而提高增长率，这比跳跃式增长模式更高。然而，蛙跳均衡和持续领导均衡的福利比较是模糊的。
In a model of endogenous growth with improvements in the quality of products, I provide a new explanation of the persistence of leadership by assuming that innovations are non-drastic and that the current leader has a move advantage in the next patent race. Under these circumstances, the value of being leader exceeds temporary monopoly profit, since the leader reaps an extra-profit in the next patent race despite free entry by outsiders. This will increase the incentive to innovate and hence the rate of growth, which is higher than in the leapfrogging model. However, the welfare comparison of the leapfrogging and persistent-leadership equilibria is ambiguous.
