I agree that there is no absolute way to write the research background and literature review chapter. however, there is a general rule of research background which is "write from general to specific". Meaning that, write your research topic general then go specific to your topic.
I take one example of finance research topic which is education loan, and it is a quantitative study (has dependent variable (DV) and independent variables(IV)). Let say I would like to study about default payment (DV) and attitude towards loan repayment (IV).
In the background of study, paragraph 1-3 i will discuss in general about education loan including the countries that offers the edu loan, the design of loan scheme etc. in the first three of the paragraphs, i didn't touch on my specific topic which is default and its predictors.
in para 4, i will discuss briefly what is wrong with the edu loan nowadays - default (refers to when someone refuses to pay loan). and briefly discussed among the major factors that may contribute to the default.
in the next 4 paragraphs, i will focus on the major factor of default which is is attitude. i explain in detail the research trend about attitude (e.g. attitudes correlated with ignorance, dissatisfaction and misconception about the consequences of not pay loan), why attitude important. why attitude towards loan repayment becomes my major focus of the study. i will cite a few recent research who said that study between attitude and intention to pay loan still limited.
the last four para, i will discuss about the evidence about default rate in my context of research (e.g. the country that you gonna do the research, e.g. UK), put some statistic, or statement from prime minister or anything else as the evidence that default is really a problem in the UK.
While, in the literature review, I will be more specific about the relationship between attitude and intention to pay loan. read as much as you can and better to put in a literature review and synthesis matrix to summarize the past research.
