The OSE research programme turns a base of 60,600+ qualified actors in 150+ countries into testable claims about how ecosystems are cultivated, governed and made inclusive — and shares the data needed to challenge them.
One base, one framework, six questions.
Regimes of enforcement, the urban module, and the overlay gradient. The integrative Level 1 — hypotheses H1 to H5.
Architecture × substance: coverage, differentiation, turnover, density, redundancy and the three coordination mechanisms (normative · resource · platform).
The Aligned Gender Index (53 countries, three dimensions) crossed with women-focused support supply. Why the correlation with density is weak, and what that implies for programme design.
Stam's ten elements as measured by the AEEI on 54 countries, re-read conditionally through COTEE — the composite as a ranking device, the profile as the diagnostic.
Affiliation, cross-affiliation and venture-level outcomes. Not yet instrumentable: needs venture-level data — the object of the call for co-authors below.
Requalification pipelines, 14 observed indicators, longitudinal press panels, network methods (Louvain, centralities, co-occurrence) at continental scale.
Claim, result on the OSE base, status. Updated as the base grows; reference values from the paper are quoted alongside.
The components of an ecosystem do not correlate and no single configuration is sufficient — an ecosystem must be read as a conditional profile.
Result · α = 0.001 between components on the OSE base; typology replicated (43 apparatus-builders · 68 endowment-based; paper 58 / 55; bootstrap stability ARI 0.631).
Replicated on 111 countries
Rule enforcement is a necessary condition for venture creation: no ecosystem creates at scale where rules do not bind.
Result · Necessity consistency 0.854 (threshold 0.80), coverage 0.775.
Replicated (fsQCA necessity)
Deliberate apparatus multiplies venture creation where rules bind and stays inert where they do not (apparatus × enforcement).
Result · Interaction β = 0.23 (p 0.076) on the OSE base vs 0.396 in the paper; predicted creation 1.3 → 6.4 (apparatus builders), 1.5 → 4.0 (endowment-based). Effect on FDI +0.60 (p 0.051); no effect on patents or high-tech exports.
Direction replicated · significance in progress
The relevant unit of an ecosystem is the urban module, not the national envelope.
Result · 68.4 % of composition variance is within countries (paper: 72 %).
Replicated (variance decomposition)
The effect of interface legibility (portals, one-stop shops) inverts with enforcement: helpful where rules are weak, harmful where they are applied.
Result · Press panel, 19 countries, 2014–2023, 154 country-years: +0.12 (n.s.) under weak rules, −0.46 (significant) under enforced rules; interaction β −0.341 (t −3.82).

Guéneau, G. et al. · Journal of Business Venturing Insights
Ecosystem advantage is a governance achievement, not a resource endowment. Three coordination mechanisms (normative, resource-mediated, platform-based) and a multi-level architecture; longitudinal evidence from seven MENA ecosystems.
Guéneau, G. · Working paper — H5 replicated on a longitudinal press panel (19 countries, 2014–2023)
The integrative Level 1 framework. Deliberate support pays off only where rules bind; the module is urban; interface legibility inverts with enforcement (H5).
Guéneau, G., Rouabeh, L., Chabaud, D. · Academy of Management Proceedings
The three-scale analysis framework: resource configurations across organizations, VRIO-consistent bundles, and the measures that Expert now computes live on the OSE base.
Guéneau, G., Chabaud, D., Chalus-Sauvannet, M.-C. · Technological Forecasting & Social Change
Longitudinal network analysis across four territories: the best-performing ecosystems rely on strong, persistent ties with practical support actors.
Guéneau, G., Chalus-Sauvannet, M.-C. · Management & Prospective (Gestion 2000)
Structure and process of a regional ecosystem co-evolve — neither can be assessed in isolation.

The Africa Entrepreneurial Ecosystem Index (Stam & van de Ven framework) is interfaced live in Expert and re-read through COTEE. Stam, E. et al. (2025). Measuring National Entrepreneurial Ecosystems in Africa. SSRN, https://doi.org/10.2139/ssrn.5254687
Worldwide Governance Indicators 2023 (rule enforcement), World Bank outcomes (new business density, FDI) and Gender Statistics (AGI inputs) feed the replications.
The Aligned Gender Index follows the Africa Gender Index structure (economic, social, representation) so that ecosystem findings can be read next to continental gender reporting.
