    This research examines the factors determining whether or not exporting firms expand to outward foreign direct investment (OFDI) as part of their internationalisation strategy, using a recent survey of Chinese private-owned enterprises. We carry out a multi-dimensional analysis to investigate the impact of firm productivity, internal resources and the external environment on OFDI decisions, including both the decision to undertake OFDI and the volume of OFDI flows. It is found that productivity, technology-based capability, export experience, industry entry barriers, subnational institutions and intermediary institutional support affect firms’ OFDI decisions. The findings have important policy and managerial implications

    Toward a unified interpretation of quark and lepton mixing from flavor and CP symmetries

    We discussed the scenario that a discrete flavor group combined with CP symmetry is broken to Z2×CPZ_2\times CP in both neutrino and charged lepton sectors. All lepton mixing angles and CP violation phases are predicted to depend on two free parameters θl\theta_{l} and θν\theta_{\nu} varying in the range of [0,π)[0, \pi). As an example, we comprehensively study the lepton mixing patterns which can be derived from the flavor group Δ(6n2)\Delta(6n^2) and CP symmetry. Three kinds of phenomenologically viable lepton mixing matrices are obtained up to row and column permutations. We further extend this approach to the quark sector. The precisely measured quark mixing angles and CP invariant can be accommodated for certain values of the free parameters θu\theta_{u} and θd\theta_{d}. A simultaneous description of quark and lepton flavor mixing structures can be achieved from a common flavor group Δ(6n2)\Delta(6n^2) and CP, and accordingly the smallest value of the group index nn is n=7n=7.Comment: 40 pages, 8 figure

    Microscopic description of octupole shape-phase transitions in light actinides and rare-earth nuclei

    A systematic analysis of low-lying quadrupole and octupole collective states is presented, based on the microscopic energy density functional framework. By mapping the deformation constrained self-consistent axially symmetric mean-field energy surfaces onto the equivalent Hamiltonian of the sdfsdf interacting boson model (IBM), that is, onto the energy expectation value in the boson condensate state, the Hamiltonian parameters are determined. The study is based on the global relativistic energy density functional DD-PC1. The resulting IBM Hamiltonian is used to calculate excitation spectra and transition rates for the positive- and negative-parity collective states in four isotopic chains characteristic for two regions of octupole deformation and collectivity: Th, Ra, Sm and Ba. Consistent with the empirical trend, the microscopic calculation based on the systematics of β2\beta_{2}-β3\beta_{3} energy maps, the resulting low-lying negative-parity bands and transition rates show evidence of a shape transition between stable octupole deformation and octupole vibrations characteristic for β3\beta_{3}-soft potentials.Comment: 18 pages, 18 figures, 1 tabl
