本文通过运用固定效应模型和工具变量方法发现,在制度越是完善的省份,越是制度依赖型的行业越具有较高的出口份额。进一步,从东、中、西分地区的估算结果来看,无论是东部还是中西部地区,制度因素仍然是影响行业出口差异的重要因素。我们还发现,在东部地区,资本禀赋是影响行业出口的重要因素,而劳动力禀赋不是影响行业出口的重要因素;在中西部地区,劳动力禀赋是影响行业出口的重要因素,而资本禀赋不是影响行业出口的重要因素;西部地区的劳动力禀赋对行业出口的影响效应似乎要高于中部地区,远高于东部地区。
Through the use of the fixed-effects model and the instrumental variables method, this paper finds that the more system-dependent sectors in the provinces where the system is more developed, the higher the export share will be. Further, judging from the estimation results of the eastern, central and western regions, the institutional factor is still an important factor that affects the export difference of the industry, no matter in the eastern or central and western regions. We also find that in the eastern region, capital endowment is an important factor affecting the export of the industry, while labor endowment is not an important factor affecting the export of the industry. In the central and western regions, labor endowment is an important factor affecting the export of the industry, while capital endowment does not affect the industry The important factor of export; the influence of labor endowment in the western region on the export of the industry appears to be higher than that in the central region and much higher than the eastern region.
