本文在一个内生增长模型的框架下分析了经济中的掠夺行为和政府的产权保护对经济增长的影响。从中发现,经济中掠夺性家户的比例及生产性家户最优的生产和保护时间取决于政府的产权保护力度,而与时间无关。政府加大产权保护力度会减少经济中的掠夺活动。同时,知识生产函数规模收益递减、不变和递增的性质使得政府的产权保护对经济的均衡增长路径以及均衡增长路径上人均产出的增长率有不同的影响。 The paper analyzes the economic predatory behavior and the government’s protection of property rights on economic growth under the framework of an endogenous growth model. It is found that the proportion of predatory households in the economy and the optimal production and protection time of the productive households depend on the government’s protection of property rights and have nothing to do with time. Increasing the government’s protection of property rights will reduce the plundering in the economy. At the same time, due to the diminishing returns to scale, the constant and increasing nature of the knowledge production function, the government property protection has different effects on the balanced growth of the economy and the growth of per capita output on the path of balanced growth.
