Retail defaults are contributing to the trend. Payless is closing 400 stores as part of a bankruptcy plan announced on Tuesday. The mammoth chain had roughly 4,000 locations and 22,000 employees -- more than it needs to handle sluggish demand.

HHGregg Inc., Gordmans Stores Inc. and Gander Mountain Co. all entered bankruptcy this year. RadioShack, meanwhile, filed for Chapter 11 for the second time in two years.

Other companies are plowing ahead with store closures outside of bankruptcy court. Sears Holdings Corp., Macy’s Inc. and JC Penney Co. are shutting hundreds of locations combined, reeling from an especially punishing slump in the department-store industry.


Others are trying to re-emerge as e-commerce brands. Kenneth Cole Productions said in November that it would close almost all of its locations. Bebe Stores Inc., a women’s apparel chain, is planning to take a similar step, people familiar with the situation said last month.

“The industry is beginning to adapt to the secular challenge of increasing online penetration,” Buss said.

But even brands moving aggressively online have struggled to match the growth of market leader Amazon.com Inc.

The Seattle-based company accounted for 53 percent of e-commerce sales growth last year, with the rest of the industry sharing the remaining 47 percent, according to EMarketer Inc.

While high-end malls continue to perform well, the exodus away from brick-and-mortar stores is taking a toll on so-called C- and D-class shopping centers, according to Oliver Chen, an analyst at Cowen & Co. There are roughly 1,200 malls in the U.S., and those classes represent about 30 percent of the total, he said.

The glut of stores is far worse in the U.S. than in other countries.

“Retail square feet per capita in the United States is more than six times that of Europe or Japan,” Urban Outfitters’ Hayne said last month. “And this doesn’t count digital commerce.”
