如果一个群体的主观幸福感（SWB）在消费方面已经达到饱和，那么就很难通过消费来提高SWB。以往的研究表明，在一些发达国家存在这种饱和现象。然而，由于缺乏数据，对发展中国家的应用情况知之甚少。因此，本研究调查消费和主观幸福感之间的关系是否存在差异，在越南的城市和农村地区之间。我们应用广义加性模型，允许一个非线性函数形式来展示消费和主观幸福感之间的详细关系。我们的研究结果表明，饱和，在物质消费方面，存在于城市地区，而在农村地区的物质消费和主观幸福感呈负相关。此外，我们发现关系型消费与主观幸福感在农村地区呈正相关，而在城市地区呈轻微的正相关或持平关系。总体而言，我们的估计结果意味着饱和的主观幸福感方面的材料消费，甚至可以观察到在发展中国家。此外，在社会资本较强的情况下，关系型消费不仅能显著提高个体的主观幸福感，而且物物交换型消费也能显著提高个体的主观幸福感。我们的研究结果表明，具有强大社会资本的共享经济可能是可持续消费的关键。
If the subjective well-being (SWB) of a population has reached saturation in terms of consumption, it becomes difficult to increase SWB through consumption. Previous studies have shown the existence of such saturation in some developed countries. However, little is known about applications for developing countries due to a lack of data. Thus, this study investigates whether a difference in the relationship between consumption and SWB exists between urban and rural areas in Vietnam. We apply the generalized additive models that allow a non-linear functional form to demonstrate the detailed relationship between consumption and SWB. Our results for Vietnam show that saturation, in terms of material consumption, exists for urban areas, while there is a negative relationship between material consumption and SWB in rural areas. In addition, we find a positive relationship between relational consumption and SWB in rural areas and a slightly positive or flat relationship in urban areas. Overall, our estimation results imply that the saturation of the SWB with regard to material consumption can be observed even in developing countries. Furthermore, not only can individuals’ SWB be significantly increased by relational consumption in the presence of a strong social capital, but the same result can be found with material consumption by bartering. Our findings imply that a sharing economy with strong social capital can be a key to sustainable consumption.
