To check for a good research topic, I suggest you do the following:
1. Choose a number of peer-reviewed research papers related to, say, cross-cultural management, from Google Scholar or similar credible websites, not from any non-credible source such as Google, etc.
2. Read these research papers and check for the research gaps from within such research. You may find these gaps under the subtitle, Future Research or similar subtitles.
3. Ensure that such gaps are not covered by recent research. That is, for the gap that you want to cover, read to the last current research in this regard to make sure that no other author(s) already conducted such research.
4. Then, go ahead and start preparing for your research, preferably using the Literature Review Matrix where you put a table showing authors, title, objectives, research question(s), problem statement, variables, methodologies used, findings, etc. for each research paper selected. By the way, you may want to keep such relevant research papers to use them as references in your research.
There are many potential research topics in the field of cross-cultural management that may be of interest to Ph.D. students. Some potential areas of focus could include:
Leadership and management styles in different cultural contexts: This could involve comparing and contrasting the leadership and management practices of different cultures, and examining how these practices influence organizational outcomes.
Communication and language barriers in cross-cultural business settings: This could involve studying the challenges and strategies for effective communication in cross-cultural business settings, including the use of translation and interpretation services.
Cultural differences in decision-making processes: This could involve exploring how cultural values and norms influence decision-making processes in different business contexts.
Cross-cultural negotiations and conflict resolution: This could involve studying how cultural differences impact the negotiation process and examining effective strategies for resolving conflicts in cross-cultural business settings.
The impact of cultural values on business practices: This could involve examining how cultural values shape business practices, such as how different cultures approach issues such as corporate social responsibility, sustainability, and ethical behavior.
Cross-cultural HR management: This could include studying issues such as diversity and inclusion, employee engagement, and talent management in cross-cultural business settings.
The impact of globalization on cross-cultural management practices: This could involve examining how globalization has influenced the way businesses to operate in different cultural contexts, and how organizations can effectively manage cross-cultural differences in a globalized world.
These are just a few examples of the many research topics that could be explored in the field of cross-cultural management. It's important for you to choose a topic that aligns with your interests and expertise, and that addresses a gap in the existing research literature.
Instead of looking for "popular" research topics in CC Management which have been amply covered, you should seek out topics for which there are gaps in our understanding, or emerging topics which you can help to advance, such as the impact of migration on CC management. As another respondent has said, this will require a lot of prior reading, but it's the only way to be sure that your subject is worth spending a chunk of your life investigating! All the best to you.
My suggestions are largely predicated on further exploration of the cultural diversities among majlr ethnic nationalities in Nigeria, with specific reference to the Igbos in southeast of Nigeria, and the Yorubas in southwest of Nigeria. Similarly a comparative study of the major ethnic nationalities in Nigeria and in Ghana. The major areas of research interests include:
i. Cultural traits and personalities of individuals and the influence on entrepreneurial effectiveness
ii. Business apprenticeship scheme and poverty reduction
iii. Cultural dimensions to time management as a most perishable asset.
