Companies with business before the city are among those contributing to the Mayor’s Fund to Advance New York City, which has been raising millions of dollars to support some of Mayor Bloomberg’s highest priority initiatives, including anti-poverty programs, public art restoration, housing, and parks.

The list of nearly 100 organizations that donated to the city’s charitable arm between October 2006 and March 2007 shows support for Mr. Bloomberg’s projects from a cross section of industries, including television and film, banking, and telecommunications.

Organizations such as Universal City Studios, JPMorgan Chase, Verizon Wireless, Rubenstein Communications, the Michael Bolton Charities Inc., and the Starr Foundation, which donated $10 million to the mayor’s anti-poverty programs, are just a few on the list. There is also one anonymous donation for $1 million or more that appears to have Mr. Bloomberg’s fingerprints on it. City Hall officials declined to comment, saying, “anonymous donations stay anonymous.”

“The mayor is himself very charitable, so this is very consistent with the way he thinks about public private partnerships,” the CEO of the private equity firm Lightyear Capital, Donald Marron, said. “I think it’s very important for all of us who can support these efforts to do so.”

Mr. Marron was one of the many who made a donation through a charitable trust.

New York-based corporations and philanthropists are paying more attention to the fund than ever. And while Mr. Bloomberg often says he is not beholden to special interests because he does need campaign contributions, the fund is one way for those with business before government to attempt to get on the mayor’s good side. JPMorgan Chase, for example, is seeking tax breaks for a new headquarters. The Starr Foundation is controlled by Maurice “Hank” Greenberg, who, along with the foundation, was the target of a probe by Eliot Spitzer when Mr. Spitzer was attorney general.

The fund’s annual revenues have grown sharply since the 1990s. It went from collecting about $3.8 million in fiscal year 1998 under Mayor Giuliani to taking in more than $17 million in 2005, highlighting the priority status it’s been given under Mr. Bloomberg. In the year after the World Trade Center attacks, it saw a one-time spike to $157 million, but the vast majority of that was for the Twin Towers Fund.

Given that Mr. Bloomberg is a former CEO who is regularly ranked as one of the most charitable individuals in the country, his mission to get private sector financing for city initiatives is not surprising.

That he and the fund’s board — which film producer Harvey Weinstein; the owner of the Mets, Fred Wilpon, and financier Steven Rattner — are part of such a high-powered circles of friends and associates only help the causes they are championing.

This year, the city has already raised at least $42 million of the $50 million it set out to raise for an anti-poverty program. It has also raised money to help protect poor New Yorkers from predatory lenders and for the conservation of the City Hall portrait collection, which contains more than 100 paintings by leading late 18th century and mid-19th century artists.

Donors who have interests in the city are not hard to find. Filings going back to October 2004 show that the lobbying firm Greenberg Traurig donated between $5,000 and $20,000 to the fund. Forest City Ratner, the developer on the Atlantic Yards project, gave between $250,000 and $499,999. And, the Indy Racing League, which is hoping to open a track on Governors Island, made a donated between $5,000 and $20,000. A spokesman for the league, John Griffin, said the league was asked to make a donation after it was granted permission from the city to stage a publicity event in Times Square.

There are also several film or television production companies who have given in the last few years, including New Line Cinema, A & E Television Networks, and Disney. Those companies are not charged fees to shoot scenes in the city, but do get regular access to city streets.

City officials said there is no link between the donations and the services provided by the city. They noted, however, that entities with an interest in keeping the production industry strong here are supportive of the efforts to promote the industry worldwide — a cause that the mayor’s Office of Film, Theatre & Broadcasting has solicited private money for.

An associate director at Common Cause, Megan Quattlebaum, said that while the fund cannot be equated to a political campaign, its roster of donors should still be watched to see if anyone is getting special treatment.

“There are all sorts of ways that money creeps into politics,” she said. “I’m skeptical of the idea that anyone is completely above influence. The old saying goes, money is like water. It always finds an outlet.”

“It’s vital to know who is giving to the fund,” Ms. Quattlebaum added. “Even though Bloomberg doesn’t take campaign contributions, there are issues near to his heart.”

The president of Citizens Union, Dick Dadey, also noted the distinction between giving to a candidate and to the fund, saying the projects the mayor is raising money for are advancing the public good — not one person’s political goals.

“I’m sure that these firms’ support for the fund does not go unnoticed, but it is done with the benefit to the public,” he said.

Mr. Dadey said disclosures, which are required by the Conflicts of Interest Board, give an appropriate amount of transparency because they allow the public to see who has made donations. “I wouldn’t want to see a limit on charitable dollars,” Mr. Dadey said.

The president of the fund, Megan Sheekey, the sister of deputy mayor Kevin Sheekey, said the fund has raised more than $124 million since Mr. Bloomberg took office.

She said that support “reflects the confidence that so many individuals, foundations, and corporate citizens have in Mayor Bloomberg” and the public programs his administration has taken on.

When asked via e-mail about donors who have business with the city, Ms. Sheekey said that fund is in strict compliance with the Conflicts of Interest Board policy.
