The president-elect has visited Alabama, Florida, Pennsylvania, Wisconsin, Michigan, Iowa, North Carolina, Ohio and Indiana, where he toured the Carrier factory.

President-elect Donald Trump appears in Indiana to salute workers at a factory where he says he saved hundreds of jobs from moving to Mexico and then in Ohio on the first stop of a “Thank You Tour” to honor the supporters in states that helped him to his stunning victory.

President-elect Donald Trump on Thursday warned that the government would punish companies seeking to move operations overseas with “consequences,” setting the stage for an unusual level of intervention by the White House into private enterprise.

Trump’s remarks came as he triumphantly celebrated a decision by the heating and air-conditioning company Carrier to reverse its plans to close a furnace plant here and move to Mexico, helping keep 1,100 jobs in Indianapolis. About 800 of those were manufacturing positions that had been scheduled to move south of the border, said a person familiar with the negotiations.

An additional 300 to 600 Carrier positions at that plant, as well as roughly 700 jobs at another facility in the area, will still be cut.

Under the terms of the agreement, which have not been finalized, Carrier would receive a $7 million tax incentive package from the state of Indiana in exchange for making a $16 million investment in the facility — although Trump said Thursday that amount would probably be higher.

In remarks delivered inside the Carrier facility, the president-elect said more companies will decide to stay in the United States because his administration will lower corporate taxes and reduce regulations. He also warned that businesses that decide to go abroad will pay a price through a border tax on imported goods.

“Companies are not going to leave the United States anymore without consequences,” Trump declared Thursday. “Not gonna happen. It’s not gonna happen.”

Trump said he decided to intervene after watching a television news report that reminded him that he had vowed during the campaign, “We’re not going to let Carrier leave.”

Trump’s determination to use a mixture of incentives and tariffs to keep jobs from going overseas represents a sharp break with the free-market wing of the Republican Party, including senior congressional leaders. On Thursday, top Republicans offered careful responses to the Carrier deal.

“I think it’s pretty darn good that people are keeping their jobs in Indiana instead of going to Mexico,” said House Speaker Paul D. Ryan (R-Wis.), emphasizing that the party is hoping to pass comprehensive tax changes that would be a boon to all businesses. Ryan has repeatedly criticized President Obama for allegedly trying to pick “winners and losers” in his stimulus package and other economic policies.

The Carrier deal was sharply criticized by some conservatives, who viewed it as government distortion of free markets, as well as liberals, who derided it as corporate welfare.

“I think it sets a pretty bad precedent,” said Dan Ikenson, director of the Herbert A. Stiefel Center for Trade Policy Studies at the Cato Institute, a libertarian think tank. “I don’t think we should be addressing issues like this on an ad hoc basis. It certainly incentivizes companies to make a stink and say: ‘We’re going to leave, too. What are you going to do for me?’ ”

Sen. Bernie Sanders of Vermont, who ran for the Democratic presidential nomination, accused Trump of reversing course on a pledge to punish companies that outsource manufacturing jobs. In the case of Carrier, Trump had said he would force the company to “pay a damn tax” if it closed the plant.

“Instead of a damn tax, the company will be rewarded with a damn tax cut,” Sanders wrote in an op-ed for The Washington Post. “Wow! How’s that for standing up to corporate greed?”

Privately, some business leaders were also unnerved.

“It is uncharted territory for a president-elect to get involved personally in social engineering with a single company,” said an adviser to major corporations, who spoke on the condition of anonymity in order not to anger the incoming administration.

Now that Carrier “is no longer the political piñata,” the adviser added, chief executives “are asking, ‘Who’s next?’ ”

Timothy Bartik, an economist at the nonpartisan W.E. Upjohn Institute for Employment Research in Kalamazoo, Mich., said that vague threats from the ­president-elect could stymie corporate investment as firms seek to avoid decisions that could draw the ire of the White House.

“What are these consequences? Who’s in charge of them?” Bartik asked.

“One of the worst things for corporate investment is uncertainty,” he added. “You would hope that the government would not add to the uncertainty.”

In Indianapolis, where Carrier has been a staple of the business community since the 1950s, the deal was celebrated.

“Our union at every level, including our local union leadership, fought to keep that plant open,” said Leo Gerard, international president of the United Steelworkers, which represents the factory’s workers.

Gerard said that although it did not endorse Trump, the union supports crucial aspects of the president-elect’s agenda, including preservation of manufacturing jobs, scrapping free-trade deals and spending on infrastructure.

“If this step is any indication of what’s to come, we look forward to working with him,” Gerard said.

Jennifer Volheim, a bartender at Sully’s Bar and Grill, down the street from the factory, said she was “heartbroken” when it was on track to shut down. But, she said, she voted for Trump and knew he would make a difference.

“We knew Trump was on it,” she said. “He’s not even in office yet and he’s saving . . . jobs.”

In fact, by Trump’s own telling on Thursday, he had no plans to intervene in the Carrier case until he watched an evening news segment featuring a worker who expressed confidence that the ­president-elect would save the Indianapolis plant. He said his campaign vow to save the plant was “a euphemism” for other companies.

Regardless, Trump — known for his tendency to react to TV news reports — said he immediately picked up the phone and called Gregory Hayes, the chief executive of Carrier’s parent company, United Technologies.

“I said, ‘Greg, you gotta help us out here. You gotta do something,’ ” Trump recalled Thursday.

Standing in front of a wall blanketed with Carrier’s blue-and-white logo, Trump lavished praise on the company for its decision, promising that the sales of its air-conditioning units would soar “because of the goodwill you have engendered.”

Experts said no modern president has intervened on behalf of an individual company. Although Obama stepped in to rescue car manufacturers after the 2008 financial crisis and President John F. Kennedy intervened to prevent steel producers from increasing prices, these actions affected entire industries — not decisions at a specific plant, Bartik said.

Jeff Windau, an analyst at the investment firm Edward Jones in St. Louis, said that Trump might not have the “bandwidth” to keep up this kind of dealmaking once in the Oval Office.

“Having a current president-elect focus on a specific company and a specific location — it’s a pretty micro view of the world,” he said.

But Trump said Thursday that he planned to personally call other companies that are contemplating moving operations out of the country, even, as he said, if critics felt such outreach was not “presidential.”

“I think it’s very presidential. And if it’s not presidential, that’s okay because I actually like doing it,” Trump said. “But we’re going to have a lot of phone calls made to companies when they say they’re leaving this country, because they’re not going to leave this country.”

Trump’s aggressive stance toward outsourcing comes despite the fact that his family companies profit from low-wage laborers around the globe who produce Trump-branded merchandise. His daughter Ivanka has her own separate brand of jewelry, shoes and clothing, much of which is produced in China.

Abigail Klem, president of Ivanka Trump’s company, said in a statement that the brand has “consistently expressed that we share industry [leaders’] interest in bringing more manufacturing opportunities to the US and are looking forward to being a part of the conversation.” A representative for the Trump Organization did not respond to requests for comment.

On the campaign trail, Trump repeatedly attacked specific companies for outsourcing, drawing huge cheers from his crowds. He blasted Ford Motor Co. for opening factories in Mexico, criticized a U.S. drug company that moved its headquarters offshore and said he would not longer eat Oreo cookies because its maker, Nabisco, moved part of its production to Mexico.

He also mocked politicians who offered low-interest loans and tax abatements to keep factories in the United States.

“These companies don’t even need the money, most of them,” he said at a rally in Wilkes-Barre, Pa., in October. “They take the money. There were a couple instances where geniuses with great lawyers gave them money, and then they moved anyway.”

Trump repeatedly pointed to Carrier’s planned move to Mexico as a prime example of the perils of globalization: The company told Indiana officials it would save $65 million a year by shifting production to a 645,000-square-foot factory under construction outside Monterrey, where wages are far lower.

Carrier rejected a tax incentive package the state offered earlier in the year to keep the Indianapolis plant open. But that was before Trump won the election and Indiana Gov. Mike Pence became the vice president-elect.

On Thursday, Hayes said that discussions with Trump and his team gave the company “a renewed confidence in the future of manufacturing” in the country.

Some state officials also noted that the federal government is a major customer of United Technologies.

United Technologies’ sales to the government have dropped in recent years, from $6.3 billion in 2013 to $5.6 billion last year, making up about 10 percent of its total revenue.

Defense analysts said that Trump could not legally steer contracts to United Technologies or punish the company through the Pentagon’s highly regulated acquisition system. The Federal Acquisition Regulations are thousands of pages long and run through an often stifling bureaucracy that determines requirements, puts out requests for proposals from industry, then embarks on a lengthy selection process that can take months, if not years.

Mackenzie Eaglen, a defense analyst at the American Enterprise Institute, said that the acquisition system can’t be used as a bargaining chip: “The short answer is no, and it would be highly illegal. Period.”
