The novel conceptual and theoretical developments in the tourism field, are closely related to a broader meta-theoretical re-orientation in contemporary sociology and philosophy, which in turn reflects some of the wider late modern social trends.

The main studies on domestic tourism are about the causal relationship between between domestic tourism and economic growth.

I've not come across much theory applied to domestic tourism (an under researched field in general). Agree that stakeholder and participation theory are useful; albeit incomplete. I think sociological perspectives are interesting also; looking at resident attitudes for instance. Yet again is frustrating how little theory there is. A massive literature gap for a brain bigger than mine I suspect!

From my point of view, domestic tourism can be both studies - demand and supply  of tourism system. If you focus on the tourists' side, understanding of what is defined as domestic tourism can be further enhance in satisfaction, experiences sought and so on. From the supply side, domestic can be explored on the  strategies that NTO  taken to harness domestic tourism. Is a top down approach initiative or bottom up approach. 

marketing strategy for development of domestic tourism and most important planning process that study is also important u have to considered geographical location theories also for study of domestic tourism 

The work is old but is very good "Tourism and Development:  Issues and Concepts".  David Telfer and Richard Sharpeley (2002 updated 2008, I think).  These two gentlemen had done an excellent job at dissecting the concepts of tourism, sustainable development and development and then cobbling together a good position that encapsulates a type of sustainable tourism.  Their posiiton is good for understanding how to craft a domestic tourism posiiton.  One thing they make clear development is unique.  .  

Thank you All for your important input.
