多年来，有几项研究评估了外国援助是否对受援国的经济增长起到了积极作用，但到目前为止，这仍然是一个悬而未决的问题。本文以日本援助中国为例，运用地理时间加权回归模型对援助的经济效益进行评价，并与普通的最小二乘法和地理加权回归模型进行了比较。研究结果表明：(1)在最小二乘模型中，日本对中国的援助出人意料地阻碍了中国的经济增长。(2)在GWR模型中，无论是援助的方向还是援助的程度，日本对华援助的有效性都呈现出明显的地区差异。(3)在GTWR模型中，援助的经济效果随着时间和空间的变化而变化。外国援助与受援国经济增长之间的时空异质性关系挑战了援助能否促进受援国经济增长的传统观念。这一发现让人们对援助的经济效益有了新的认识。
Over the years, several studies have assessed whether foreign aid plays an active role in promoting economic growth of the recipient country, but to date, it is still an unresolved question. Based on the case of Japan's aid to China, this paper uses the geographically and temporally weighted regression (GTWR) model to evaluate the economic effect of aid, compared with the ordinary least squares (OLS) and geographically weighted regression (GWR) models. The results reveal the following: (1) In the OLS model, Japanese aid to China surprisingly hampered China's economic growth. (2) In the GWR model, the Japanese aid's effectiveness appears a noticeable regional differentiation in line with both the orientation and extent of aid. (3) In the GTWR model, however, the economic effectiveness of aid changes both over time and in space. The spatiotemporal heterogeneous relationship between foreign aid and economic growth in a recipient country challenges the traditional belief that aid either can or cannot promote the recipient country's economic growth. This finding provides a new perception of the economic effectiveness of aid.
