ABSTRACT
This study examines tourism convergence across regions within a country as a means to understand the extent to which there is segmentation of regional tourism markets and the differential impact of domestic versus foreign tourism. Additionally, our empirical analysis introduces a newly developed weak σ-convergence test alongside the club convergence approach to explore regional tourism convergence. Using disaggregated monthly county-level data for Croatia from 1998:1 to 2021:9, the results clearly identify the divergence across counties to suggest the regional segmentation of tourism in the country between coastal and continental regions. The policy implications of the results are also discussed.

4 Together with the recovery and resilience plans of the other 26 EU countries, it is a part of a wide-ranging response of the European Union to the negative economic and social impacts of the COVID-19 pandemic.
5 Hence, unlike the previous studies, we assume that the absence of convergence does not necessarily imply divergence since there is the possibility for the prevalence of convergent clubs across counties.
6 This division corresponds to the European Union official division for regional statistics at NUTS-3 level (NUTS-nomenclature of territorial units for statistics). parallels the presentation of the Croatian county map by Gil-Alana, Mervar, and Payne (Citation2015) and Apergis, Mervar, and Payne (Citation2017).
7 Since the log-t function is rapidly increasing initially, Phillips and Sul (Citation2007) suggest eliminating the first third of the sample in recommending r = 0.3. It is worth noting that since ut is serially correlated, Phillips and Sul (Citation2007) employ the HAC (heteroscedasticity and autocorrelation consistent) long-run variance estimator proposed by Newey and West (Citation1987) to construct the robust t-statistic.

9 Before proceeding with inferences, the Hodrick and Prescott (Citation1997) filter was applied to the natural log transformed data for removing (seasonal and business) cycles in the data (see Phillips and Sul Citation2007, Citation2009).
10 Note four different truncation parameter settings are used (L = 3, 6, 9, 12) for the construction of the Newey and West (Citation1987) HAC long-run variance.

12 We also examined the results for the pre-COVID-19 period. The results for relative (club) convergence and weak σ-convergence still support divergence similar to the results inclusive of the COVID-19 period presented. Results are available upon request.
13 As shown at the bottom of , the principal components explain 90, 97, 81, and 96% of total variance for DOMAR, FORAR, DOMON, and FORON, respectively.
14 We are grateful to the anonymous reviewer for pointing out the need for robustness analysis by conducting other convergence tests. We estimate convergence models for absolute β-convergence with a battery of panel data estimators with common factors; and for stochastic convergence with a battery of panel stationarity tests, including both conventional first-generation tests without cross-section dependence and second generation tests with cross-section dependence. The results presented in the Appendix indicate that although the absolute β-convergence is supported overall, stochastic convergence is not supported consistent with the evidence in favour of divergence from relative and weak -convergence approaches.
