Gabon's decision to stop exports of forestry raw materials and to develop an industrialization strategy made it possible to apply certain theories of regional growth. The creation of the Nkok Special Economic Zone in 2012 (considered a homogeneous space unlike the external zone of the SEZ, considered heterogeneous) and the improvement of infrastructure illustrate the use of Rosenstein-Rodan's "Big push" theories and the Douglass North export base). These investments have fostered a process of unbalanced economic polarization, as theorists such as François Perroux have studied. Thanks to the use of the “Bias-Corrected Estimation of linear dynamic panel data” model, the analysis of industrial and commercial relationships and mechanisms during the period 2014-2022 show that the homogeneous space has positively influenced the heterogeneous space and the macroenvironment. This led to an increase in industrial income linked to exports, except for forestry products due to the ban on the export of raw materials. Export revenues boosted industrial production, while an increase in industrial revenues led to a decline in raw material exports, favoring domestic processing. The study makes it possible, using data from short and unbalanced panels, to carry out suitable estimation methods by establishing a decision-making process which results in an optimal model to be used for modeling spatial imbalance. This polarization process needs to be further studied to understand long-term economic and geographic imbalances in developing countries.
