What matters? Abstract This article deals with the border effect phenomenon affecting the mobility of inhabitants in border regions. It aims to identify the determinants of the border effect in transport at the municipal level, considering the distance from the border, the populations and the characteristics of the closest bordering country. The survey in the Czech Republic eventually involved 675 representatives of municipalities who answered questions on inter-municipal mobility. The results confirmed that the most substantial handicap was population size, with small populations corresponding to the limited use of public transport when travelling beyond a given border. The results confirmed that the characteristics of the state or region that shares the border must be considered when assessing border regions. Therefore, the solution to the problems of individual border regions cannot be viewed with a single instrument. It is necessary to consider substantial differences resulting from the economic level of neighbouring countries.

In identifying potential barriers, w h i c h are an e s s e n t i a l issue in border a r e a s , the literature d i s c u s s e s the p h e n o m e n o n of the border effect. T h e border effect w a s originally defined a s r e d u c e d trade c a u s e d by the e x i s t e n c e of international borders (Havranek & Irsova 2016) a n d the first author w h o formulated the idea of the border effect w a s McCallum (1995). Within C e n t r a l a n d E a s t e r n E u r o p e , the border effect w a s higher before the Velvet Revolution d u e to the low permeability of borders. In the 1 9 9 0 s , c r o s s - b o r d e r c o o p e r a t i o n e m e r g e d in the C z e c h R e p u b l i c with the e s t a b l i s h m e n t of E u r o r e g i o n s a n d the abolition of border controls, a n d d e v e l o p e d further t h a n k s to the a c c e s s i o n to the S c h e n g e n A r e a in 2 0 0 7 (Drapela & Basta 2018). T e c h n i c a l barriers a n d regulatory a s y m m e t r i e s a c r o s s countries m a y explain the b o r d e r effect, t h o u g h that is not the c a s e for the E u r o p e a n U n i o n (Turrini & van Ypersele 2010), w h e r e the effects of negative borders s e e m to b e in d e c l i n e s i n c e the creation of the c o m m o n market (Rietveld 2012). M o r e o v e r , it h a s b e e n a c k n o w l e d g e d that c o n s u m e r s prefer g o o d s from their h o m e region rather than products from other regions (Balaguer & Ripolles 2018). T h e border effect is usually quantified by a gravity m o d e l of spatial interactions a m o n g countries (Klodt 2004), w h i c h s u c c e s s f u l l y e x p l a i n s trade flows (Hazledine 2009). T h e border effect w a s initially studied in air transport, w h e r e it w a s s h o w n to lead to d i m i n i s h e d v o l u m e s of flights on international airline c o n n e c t i o n s . Zijlstra (2020) e x a m i n e d the border effect in airport c h o i c e in W e s t e r n E u r o p e a n d confirmed the expectation of a negative barrier effect of national borders in transport g e o g r a p h y . P e o p l e preferred to c h o o s e a departure airport situated in their o w n country. Similarly, Klodt (2004) found a negative b o r d e r effect of G e r m a n borders o n departures from G e r m a n airports. H e c a m e to the c o n c l u s i o n that g e o g r a p h i c a l d i s t a n c e a n d national borders continue to matter (2004: 526). Hazledine (2009) a s s e s s e d the border effect using the e x a m p l e of C a n a d i a n air travel a n d found that C a n a d a is c o n s i s t e n t with the effects of borders d e t e r m i n e d in other studies of international m e r c h a n d i s e trade. Medeiros (2019) dealt with c r o s s - b o r d e r mobility that w o u l d b e i n c r e a s e d with the p r e s e n c e of c r o s s - b o r d e r transport. H o w e v e r , c r o s s - b o r d e r transport is not yet sufficiently d e v e l o p e d to satisfy the increasing n e e d s of E u r o p e a n citizens to c r o s s b o r d e r s , a n d c r o s s - b o r d e r c o m m u t i n g is still at a low level (Buch, Schmidt & Niebuhr2009).
