Land expansion and growth in low‐ and middle‐income countries*

Over past decades, low and middle‐income countries have experienced considerable expansion of agricultural land, yet this effect on growth has not been examined The following paper shows that the Solow‐Swan growth model can be extended to the case whereby arable land is expanding, as originally suggested by Solow (1956). This extension indicates that land expansion boosts growth, and this effect increases with the relative share of land in income. An empirical analysis over 1990–2018 for 138 low and middle‐income countries supports this finding. The growth impact of land expansion over 1990–2018 varied significantly across the sample of countries depending on how much income was derived from land. This result explains why countries dependent on agriculture have engaged in extensive land expansion: it boosts overall growth. However, these growth benefits must be weighed against the considerable environmental costs of converting forests and other natural habitat to more agricultural land, such as increased carbon emissions, loss of ecosystem services and biodiversity, risk of disease, and impacts on local livelihoods.

中低收入国家的土地扩张与增长*

在过去的几十年中,中低收入国家经历了可观的农业用地扩张,但是对增长的影响尚未得到研究。以下文件显示,Solow-Swan增长模型可以扩展到耕地在扩张的情况下,如Solow(1956)最初提出的那样。这种扩展表明土地扩张促进了增长,并且这种效应随着土地在收入中的相对份额而增加。1990年至2018年间对138个中低收入国家的实证分析支持了这一发现。1990-2018年间,土地扩张对增长的影响在各个国家样本中差异很大,这取决于土地收入多少。这一结果解释了为什么依赖农业的国家进行了广泛的土地扩张:这促进了总体增长。然而,
