Shida area shuts off lights in protest - Taipei Times

7. Shida Case
Local Residents: Local residents are emphasizing that the Shida district has long been designated as a “cultural and educational region” and claim that all they want is to restore peace and serenity in a cultural environment.
City Government: Following a protest by residents of the area in October 2011, Taipei Mayor Hau Lung- bin announced that‘ no further expansion of the Shida Night Market would be permitted‘. Citing by rule that states commercial services as restaurants, retail stands and shops are not allowed to be operated in lanes with a width of under 6 meters.
Shop/Restaurant Owners: In April 2012, the city began its first wave of inspections and finds. More than 400 stores in the area switched off their lights for 30 minutes to protest against the forced closures of stores in the area, in hopes that it would persuade the Taipei City Government to listen to their pleas and offer a channel of communication.

8. Negative Externalities
Increased pollution (waste, noise, smell)
Increased traffic in the neighborhood, harder for pedestrians and vehicles to transit, crowded MRT stations.
Disputes between communities and night markets, government must intervene, more work for government (Shida).
Department stores lose customers to night markets.
Real estate of surrounding property goes down in some cases.

What can the government do to diminish the negative externalities of noise, smell and waste pollution caused by the night markets?

10. Possible Strategies Have more garbage cans.
Cleanup tax on the business owners.
Fees or tickets for littering.
Zoning laws to separate residential from commercial.
Separate clothing section from food section.
Provide incentives, like tax cuts and awards for businesses that follow proper disposal of wastes.
