Rachel Reeves says she won't let critics "get me down" after a rocky few days for the UK economy.
The principal is Nick Robinson interviewed by BBC Political Thoughts Towards the end of the week, the country's borrowing costs rose to their highest level in years.
Reeves said the rise was "not a British phenomenon" and that other countries had also seen rising borrowing costs.
She also insisted that she "knows the idea of contributing to the people of this country" and "turning things around".
Thursday's data showed UK economy grew 0.1% in November This has heightened concerns that growth may remain stagnant for some time to come.
The Conservatives accused the chancellor of "burying his head in the sand" and called for an "urgent change of course".
Lib Dem Treasury spokesperson Daisy Cooper said Reeves had "put a handbrake on the economy with a misleading employment tax" - ref The rise of national insurance Paid by the business.
Speaking to the BBC, Reeves said current levels of growth were "not good enough" and that improving the numbers was "a priority for the Labor government".
As part of that mission, Reeves said she would meet with regulators to encourage them to "take necessary steps" to promote growth.
"If regulators continue to do this, we won't be able to grow our economy."
She added that there were no "rooms big enough" to meet all UK regulators' requirements.
Since taking office in July, Reeves has faced criticism for a number of decisions, including Eliminate winter fuel charges All but the poorest pensioners, Changes to inheritance tax rules for farmers and Choosing not to compensate women Affected by changes in state pension ages.
She argued the moves were "difficult decisions" but the "right ones in the national interest".
She added that she wished she had been told "'the money is coming'... then I could have made a different decision" when she first arrived at the job.
"But in the case of my inheritance, I judged that I had to make sure that the money added up."
Asked whether her decision had hurt business confidence, Reeves asked: "What's the alternative?
“All decisions have consequences, but imagine the alternative.
"Imagine if I hadn't addressed this, now when financial markets look at Britain they're going to say 'This is a government that's not truthful about the situation it's facing and it's spending more money than it's bringing in. .It has to borrow more and more money.”
Asked about the criticism she faced, Reeves said: “I don’t take it personally.
"There are people who don't want me to succeed. There are people who don't want this administration to succeed."
The chancellor added: "That's fair enough. That's their prerogative. But I'm not going to let them let me down. I'm not going to let them stop me from doing what this government has the power to do, and that's growing the economy."
