He uses a formula like this one: C(i,j) = O(i) * O(j) ...where C(i,j) is the total connectivity between actor i and j and where O(i) and O(j) are total number of TNC offices of actor i respectively j. In short, what is done here is an estimation of the structural value between dyads based on internal attributes of the actors. If city i has 2 offices and city j has 3 offices, the structural connectivity value between i and j is set to 6, thus implying the total number of links between these two actors. Is this a common way of fetching structural data, i.e to use actor attributes like this? Intuitively, what regards Taylor's study, it feels like a reasonable good approximation of the structural data but when it is only based on actor-internal attributes, I also get the feeling that it isn't following a very 'networkish' style!
