Wien is very similar to Budapest in size and facility. In 1992 Wien established a shopping street management network. They support those streets that join their “forces” to make their own environment and business better. If they establish an association then the Chamber of Economy of Austria gives a manager to the street. Members can be merchants, companies or even public organizations (like schools, church, kindergarten etc). The main task of the manager is to keep the information flowing. But also they do marketing tasks, organizing events, or help to keep the streets clean and the shops rented. They work together with the members, making brainstorming events and information days.
We had the chance to see that in person during a 2 weeks long study tour.
In 2013 there were 80 shopping streets in Wien with 8000 members and 39 shopping street managers. It means 100 associations and 20 000 shops with 120 000 workers. Their total turnover is around 9,5 Billion EUR/year.
