This research has in sight the Bihor – Hajdú-Bihar Euroregion located at the border between Romania (in the north-western part) and Hungary (in the east). The research methodology that was used consisted in the statistical data collection in order to gather representative information on the evolution of tourism for the 2008 – 2011, in Bihor – Hajdú-Bihar Euroregion. In the first part of the research is presented an analysis regarding the evolution of the number of tourists within the tourist accommodation establishments in the Bihor – Hajdú-Bihar Euroregion. The analysis is based on the following aspects: the evolution of the number of tourists within the Bihor – Hajdú-Bihar Euroregion is presented; a comparison regarding the number of national tourists registered in the two counties belonging to the Bihor – Hajdú-Bihar Euroregion and finally an analysis based on the number of foreign tourists registered within the two counties belonging to the Bihor – Hajdú-Bihar Euroregion. In the second part of the research, the study continues with the analysis of the activities of the hotel units from Bihor and Hajdú-Bihar starting from the data obtained from the Bihor County Statistics Department, for Bihor County, and from the Debrecen Central Statistics Office, for the Hajdú-Bihar data. The research covers the period from 2008 – 2011, following the indicators regarding: the number of active units, turnover, and employee related expenses, staff and gross investments in tangible assets. This statistical and economic analysis presents on one hand the centralization of the indicators used within a table, (initially, in a rough form and subsequently in a shaped form based on the annual average exchange rates of the leu and forint compared to the euro during 2008-2011) and on the other the evolution of each indicator in chart form. Due to the fact that a part of the analyzed indicators are expressed in the national currency of the two countries (Romania and Hungary), I have used the annual average exchange rates of the leu and forint compared to the euro, in order to bring them to comparable units of measurement. The sources of information for these were the websites of the National Bank of Romania, for the annual average leu/euro exchange, and The Central Bank of Hungary for the annual average forint/euro exchange rate.
