本文提出了一个具有经济结构和地理位置的开放型小城市的增长模型。位于沿着的城市有工业、服务业和住房三个部门。小城市空间增长模型综合了新古典增长理论、城市经济学和小型开放经济体经济增长理论中一些重要模型的主要思想。我们证明了动力系统有唯一的平衡点。我们还模拟了城市经济在时间和空间上的运动。我们的方法的独特之处是把生产活动、经济结构、居住分布、资本积累和消费作为一个整体，在微观经济机制的基础上进行处理。我们的模拟提供了一些重要的见解城市经济增长的过程。例如，在一定条件下，当工业部门的生产率提高时，服务业和工业部门的工资率、服务价格、资本密集度以及这两个部门的人均产出水平也会提高。劳动力供给总量、三大部门的资本存量以及服务业和工业部门的劳动力都有所增加。这三个部门的份额在长期内不受技术变革的影响，即使它们的份额最初受到影响。工业品人均消费水平上升，服务业福尔斯消费水平下降。土地和住房租金上涨，每户住房消费福尔斯下降。此外，经常项目收支趋于顺差，增长率提高。
This article presents a growth model of a small open city with economic structure and geography. The city which is located along a line segment has three, industrial, services and housing, sectors. The spatial growth model of a small city synthesizes the main ideas in some important models in the neoclassical growth theory, urban economics, and the literature of economic growth of small open economies. We show that the dynamic system has a unique equilibrium. We also simulate the motion of the urban economy over time and space. The unique feature of our approach is to treat production activities, economic structure, residential distribution, capital accumulation, and consumption on the basis of microeconomic mechanism as an integrated whole. Our simulation provides some important insights into the processes of the urban economic growth. For instance, under certain conditions, when the industrial sector’s productivity is increased, the wage rate, price of services, capital intensities of the services and industrial sectors, and per-worker output levels of the two sectors are increased. The total labor supply, the capital stocks employed by the three sectors and the labor forces by the service and industrial sectors are all increased. The shares of the three sectors are not affected by the technological change in the long term, even though the shares are initially affected. The per capita consumption level of the industrial goods rises and the consumption level of services falls. The land and housing rents are increased and the consumption of housing per household falls. Moreover, the current account balance tends to be more in surplus and the growth rate is increased.
