Dublin City Council research has shown that feeling unsafe was one of the biggest factors negatively influencing people's experience of the city centre.
A new initiative to reduce the visual impact of beggars is being run by the Dublin City Business Improvement District (BID) and charity Tiglin.
The Change for the Better campaign is a "diverted giving" scheme, where people are being asked to donate to one of 40 charity boxes in shops and businesses around the city instead of giving money to beggars.
BID and other businesses have offered to match the public donations in the boxes.
Chief executive Richard Guiney said active begging is "a serious problem" in the centre, adding: "There has been a stark increase in the number of active begging incidents recorded in the BID area over the past year.
"We have also observed cases of professional begging in the city, where money given by the public was used to buy drugs."
Funds raised will go to addictions charity Tiglin. The group's Phil Thompson said it will be an educational process for beggars and the public.
