This network had been formed before 1974, during the dictatorship, but it remained after the Carnation Revolution. In spite of such research, this network has not yet been properly analysed, especially through adequate tools from network analysis. This work will detail this network, the different scores of centrality of each company, and their modular structures; it will also discuss estimates from exponential random graph models to identify significant attributes that explain the discovered flows of investment. This work will also detail the processes of vertical integration as well as the specificities of the identified oligopolies.<\/jats:p>","DOI":"10.1017\/s1062798721000272","type":"journal-article","created":{"date-parts":[[2021,12,13]],"date-time":"2021-12-13T08:44:15Z","timestamp":1639385055000},"page":"725-748","source":"Crossref","is-referenced-by-count":0,"title":["The Portuguese Hub of Companies in 1973 \u2013 Discussing the Corporate Concentration in the Portuguese Economy on the Eve of the April Revolution"],"prefix":"10.1017","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6046-645X","authenticated-orcid":false,"given":"Paulo","family":"Reis Mourao","sequence":"first","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2021,12,13]]},"reference":[{"volume-title":"O Investimento Estrangeiro em Portugal","year":"1973","author":"Salgado de Matos","key":"S1062798721000272_ref32"},{"volume-title":"Evolu\u00e7\u00e3o Da Economia Portuguesa (1963\u20131966)","year":"1967","author":"Guerra","key":"S1062798721000272_ref39"},{"key":"S1062798721000272_ref19","unstructured":"Macedo, J , Corado, C and Porto, ML (1988) The timing and sequence of trade liberalization policies: Portugal 1948\u20131986.
