Mark Prisk, the housing and local government minister, told the Daily Telegraph shop owners must do more if they are to win back customers who have turned to the internet.
The warning comes as the Department of Communities and Local Government today awarded seven towns a share of £1 million in return for successfully breathing new life into their high streets.
Mr Prisk said the Government is doing "all it could" to help shops survive, including reducing business rates and encouraging local councils to be more flexible with parking.
"We will keep providing support where it is needed, but it takes more than funding to make this work," he told the Daily Telegraph.
"As consumers, our behaviour has changed. High streets need to respond to that change if they are to prosper."
More than 2,100 jobs have been saved by Sports Direct International's purchase of 116 stores from fashion retailer Republic.
The Sports World group has also taken over the stock, along with the group's head office in Leeds and its websites and brands SoulCal, Fabric and Crafted.
Britain's retailers have faced yet more gloomy predictions today with up to half of major High Street stores planning to cut staff, according to a new survey.
The grim outlook comes in the wake of a series of famous names going under, like Jessops, Blockbuster and HMV.
ITV News Consumer Editor Chris Choi reports from Warrington:
Around 50 per cent of retailers will shed jobs in the first quarter of 2013, according to research by the British Retail Consortium.
Speaking to ITV Daybreak, Employment Minister Mark Hoban said that the overall employment figures are good, and that jobs are being created.
He added that the high street is changing and job descriptions will change too.
The British Retail Consortium has reported that more than half of high street stores will be making staff cuts this spring.
ITV Daybreak spoke to Fiona Wilson from the Union of Shop, Distributive and Allied Workers, she said: "We would expect to see some seasonal changes in the new year".
Half of all shops on the high street plan to cut staff over the next few months, as many struggle to stay afloat.
The warning from the British Retail Consortium comes as thousands of shop staff, made redundant since Christmas, try to find work.
ITV Daybreak's Katy Fawcett reports.
High streets are facing challenges such as the rise of internet shopping, which is why the Government is offering practical support. That's why we've doubled the amount of small business rate relief and extended it for a year to help up to half a million new and smaller shops.
For budding entrepreneurs, we're providing over £80 million of start-up loans for young people starting their own businesses.
The fact that total employment edged up during this quarter, driven by part-time workers, is a shaft of light against an otherwise challenging backdrop.
It shows that, despite relentlessly tough times, retailers are continuing to invest in people and support job creation as much as they can.
But the record drop in store numbers is stark evidence that this investment should not be taken for granted. We're by no means out of the woods yet, and given the administrations of recent weeks, the next quarter's figures are likely to make difficult reading.
Around 50 per cent of retailers said they planned to cut staffing levels in the next few months, with only 4% expecting to create jobs, according to a new survey.
There were also almost 600 fewer shops last month even before the recent collapse of a raft of High Street names, according to the British Retail Consortium (BRC).
However, employment in the retail sector rose by 0.6% in the final quarter of 2012 compared with a year earlier, driven entirely by part-time workers, the study found.
The survey, covering 1.3 million workers at 25 major retailers, showed that Christmas was not a disaster for traders, but staffing levels were kept "modest".
