消费者异质性与贸易利益的个体分配效应研究：理论与中国经验

On the basis of consumer heterogeneity, this project aims at promoting the theory and empirical research on the individual distributional effects of gains from trade through the expenditure channel. After analyzing and comparing the properties and empirical correlation of various utility function under non-homothetic preferences assumption, we’ll use the multidimensional properties of consumer heterogeneity assumption, especially the spatial heterogeneity and age heterogeneity, to establish the general equilibrium model that fits with China’s economic characteristics. And considering different forms of trade liberalization, different trade mode, the domestic market segmentation and intermediary organization in China, we’ll discuss how the transmission mechanism and efficiency affect the distribution of trade gains on individuals. Nesting the two-side heterogeneity, the model may compare the different contributions between income and consumption effects, decompose trade gains structurally, and ultimately identify the source of individual difference in trade gains. Further more, we’ll conduct empirical research through the calibration tests and parameter simulations of general equilibrium model and econometric methods with multiple data to study the individual distributional effects of trade gains. This project not only serves to design the scientific and equitable redistribution policy and implement related policy reforms but provide scientific theoretical basis for China to "develop a higher level of open economy", to achieve "inclusive growth", "shared development" and to enhance the people's "sense of acquisition".

本项目将基于消费者异质性，从消费渠道推进贸易利益个体分配效应的理论与经验研究。深入分析和比较非同位偏好下各类效用函数的性质与经验相关性；拓展消费者异质性的多维假定，重点是空间异质性与年龄异质性，以完成更符中国特征的一般均衡模型构造，讨论不同形式的贸易自由化、不同的贸易方式、国内市场分割、中间商组织等更符现实情境下，贸易利益个体分配的传导机制与传递效率；嵌入双侧异质性，探究收入效应与消费效应的差异化贡献，实现贸易利益的两种结构性分解，最终厘清贸易利益个体分配的来源。进一步的，采用多数据、多方法，完成若干经验计量和一般均衡模型的校准试验与参数模拟，展开对中国贸易利益个体分配效应的相关经验研究，以探寻科学而公平的再分配政策设计及相关配套政策改革，为中国“发展更高层次的开放型经济”，实现“包容性增长”、“共享发展”和增强人民群众的“获得感”，提供科学的理论依据。
