中文摘要:研究认为我国居民消费意愿偏低(这与改革开放前收入增长速度低,而改革开放后收入差距扩大等因素相关)导致的高储蓄率是造成我国投资率居高不下的重要影响因素;并且我国处于工业化以及城市化进程的早期阶段,客观上要求比较高的投资率来维持经济的快速增长;但近年来的研究表明我国无论是改革开放前还是改革开放后投资率与国内生产总值(GDP)之间并不存在互相推动或互相拉动的关系,而表现为较高的同期相关性,我国近年来居高不下的投资回报率是造成我国投资率长期高于同期其他国家(如美国和日本等国)的根本原因;据此我们认为,解释我国投资率进而储蓄率高、这一高储蓄率是否合理以及可持续性程度如何的最为核心的因素是资本投资的回报率,我们将从全要素生产率变动这一关键因素来分析造成我国储蓄率水平及变动趋势的原因,并且从这一角度来阐释我国目前的储蓄率水平是否“过高”,我们的研究结果指出:首先全要素生产率变动是影响我国储蓄率水平以及变动趋势的非常重要的因素;其次我们发现我国的储蓄率水平并不高,甚至于在1952年以来的绝大多数年份处于“储蓄不足”的局面。
Abstract:
China
’s economic growth over the past three decades ranks as the most rapid sustained increase in documented global history. Although this growth is commonly attributed to a high domestic savings rate among “thrifty” Chinese, savings alone cannot promote economic growth unless productivity has continuously grown during the same period. This article uses a one-sector, neoclassical growth model to calibrate the economy to Chinese data since 1952 and finds that measuring changes in the total factor productivity between 1952 and 2005 can well capture the secular movements in the Chinese savings rate. Far from supporting the widespread belief that
China
’s savings rate is too high, this article argues that even thrifty Chinese undersaved for most of the years during this period and that the fiscal reforms of 1983 and 1985 further suppressed saving behavior, especially when initially implemented. In presenting such findings, this article at least partly solves the so-called Chinese savings puzzle.
