異質(zhì)性企業(yè)貿(mào)易理論是否服從盧卡斯批判

【摘要】:本文通過對異質(zhì)性企業(yè)貿(mào)易理論的探討,構(gòu)建可變貿(mào)易成本與生產(chǎn)率聯(lián)合異質(zhì)性的一般均衡模型,解釋異質(zhì)性企業(yè)貿(mào)易理論的產(chǎn)品多樣性、社會福利以及企業(yè)選擇的基礎(chǔ)理論問題。研究發(fā)現(xiàn),Melitz模型的參數(shù)限制區(qū)間在生產(chǎn)率無上界的帕累托分布下存在,在有上界的帕累托分布中消失;對社會福利的分解證明了自由貿(mào)易度提高會降低總的開放經(jīng)濟產(chǎn)品多樣性。存在異質(zhì)性可變貿(mào)易成本拓展模型,證明了市場分割未必會阻礙社會福利的增長。此外,可變貿(mào)易成本的提高會顯著提升企業(yè)出口概率,從而社會福利的增長機制會出現(xiàn)與Melitz模型不一致的情況。
[Abstract]:Based on the discussion of heterogeneous enterprise trade theory, this paper constructs a general equilibrium model of variable trade cost and productivity heterogeneity, and explains the product diversity of heterogeneous enterprise trade theory. Social welfare and the basic theory of enterprise choice. It is found that the parameter limiting interval of the Melitz model exists under the Pareto distribution of the supreme productivity bound and disappears in the upper bound Pareto distribution. The breakdown of social welfare demonstrates that increased free trade reduces the overall diversity of open economy products. The existence of heterogeneity variable trade cost expansion model proves that market segmentation does not necessarily hinder the growth of social welfare. In addition, the increase of variable trade costs will significantly increase the export probability of enterprises, thus the growth mechanism of social welfare will be inconsistent with the Melitz model.
