@Sagarika Acceptability and publishability of a research depends on what research problem it's addressing, whether enriching the existing body of knowledge in that domain of research, sticking to the scope of journal, employes appropriate methods (irrespective of secondary/primary data). If you have reviewed a need of such kind of study in the domain and your study promises some contribution to the literature than yes it's publishable provided you present your research as per the standards of the journal.
Many issues and factors are involved here for any sensible statistical analysis. 1. What do you intend to prove? 2. What types of relevant factors you are considering? 3. What types of statistical analysis you want to do? 4. Time series or cross-section? 5. What types of exogenous and endogenous factors are important here? 6. Context of analysis? 7. Recessionary time or expansionary time? So many complex factors.
Accepting the pre-requisite of the aforesaid answers.
It is also important to notice that the secondary data if from the reliable and globally accepted source.
Most of the people would have used secondary data, to find a different result using different attributes/variables.
If the findings from the reliable secondary data makes a difference in decision taken or solves a greater problem practically, then that's what is expected.
