【摘要】：本文在Bilbiie等(2012)带有企业自由进入的框架下,建立一个包含资本密集型和劳动密集型两个行业的DSGE模型,分析了技术进步和进入门槛变化带来的经济波动如何在不同行业间进行传导。本文从扩展边际(部门企业数目变化)和集约边际(单个企业产量变化)两个角度进行研究。研究发现,不同冲击对企业数目和单个企业产出的影响大小,与不同要素在企业进入成本的复合比例相关。具体而言,资本密集行业技术进步,在带来资本密集行业产出增加的同时,改变了两部门商品的相对价格和两部门的进入成本,使得劳动密集行业产出下降,但是资本密集行业和劳动密集型行业企业数目同时都增加;资本密集型行业进入门槛下降,大量企业进入资本密集型,资本密集型行业企业数目和产出都增加,同时通过要素价格上升,使得劳动密集型部门企业数目和产出下降。
[Abstract]:In this paper, under the framework of Bilbiie et al. (2012) with the free entry of enterprises, we establish a DSGE model with capital-intensive and labor-intensive industries. This paper analyzes how the economic fluctuation caused by the technological progress and the change of entry threshold is transmitted among different industries. In this paper, the extended marginal (number of sector firms) and the intensive marginal (single firm output change) are studied. It is found that the impact of different shocks on the number of firms and the output of a single firm is related to the composite proportion of different factors in the entry cost of the firm. In particular, technological advances in capital-intensive industries have brought about an increase in the output of capital-intensive industries, while changing the relative prices of commodities in both sectors and the cost of entry into the two sectors, which has led to a decline in the output of labour-intensive industries. However, the number of enterprises in both capital-intensive and labour-intensive industries has increased at the same time; the threshold for entry in capital-intensive industries has decreased, a large number of enterprises have entered capital-intensive industries, and the number and output of enterprises in capital-intensive industries have increased. At the same time, through the factor price rise, the number of enterprises and output in labor-intensive sectors decreased.
