Geometric and summability properties of the integration operator associated to a vector measure m can be translated in terms of structure properties of the space L1(m). In this paper we study the cases of the integration operator being: (i) p-concave on Lp(m), or (ii) positive p-summing on L1(m) (where \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$1 \leq p < \infty$$\end{document}). We prove that (i) is equivalent to saying that L1(m) contains continuously the Lp space of a (non-negative scalar) control measure for m. On the other hand, we show that (ii) holds if and only if L1(m) is order isomorphic to the L1 space of a non-negative scalar measure.
