Spatial proximity and firm performance: evidence from non-farm rural enterprises in Ethiopia and Nigeria
作者研究了埃塞俄比亚和尼日利亚农村非农企业的空间邻近性对企业绩效的影响。使用2011年埃塞俄比亚农村社会经济调查和2010/2011年尼日利亚一般家庭调查的地理参考数据，通过探索性空间数据分析，发现两国企业绩效存在显著的空间聚类。进一步用企业间平均距离度量空间依赖，结果表明，在控制家庭、企业和社区特征后，空间邻近性对企业生产率有重要解释作用。
Spatial proximity and firm performance: evidence from non-farm rural enterprises in Ethiopia and Nigeria. Regional Studies. The productivity of non-farm enterprises in rural Africa can be associated with the productivity of other spatially proximate non-farm enterprises. To test for the presence and significance of such spatial autocorrelation, the article uses data from the georeferenced 2011 Ethiopian Rural Socioeconomic Survey (ERSS) and the 2010/2011 Nigeria General Household Survey (NGHS), and employs exploratory spatial data analyses. There is evidence of significant spatial clustering of firm performance in both countries. This spatial dependence is empirically modelled using average distance measures between firms. It is found that in addition to other household, firm and community characteristics, spatial proximity between firms plays an important role in explaining firm productivity in Nigeria and Ethiopia.
