HONG KONG —Despite a slowdown in China, Alibaba, the Internet giant, experienced a surge in revenue in the latest quarter, driven by strong growth in mobile.

Given Alibaba’s dominance in online shopping, investors have been concerned that the trouble in the country’s economy could spill over into the company’s performance.

After its much-hyped initial public offering last year, Alibaba reported lackluster earnings in the first half of 2015. Its stock price even briefly dropped below its listing price.

Now Alibaba is showing signs of stabilizing.

In its results on Tuesday, Alibaba reported that sales rose 32 percent in the latest quarter to 22.2 billion renminbi, or $3.5 billion. Earnings per share increased 30 percent. After Alibaba reported results on Tuesday, the company’s stock jumped 5 percent in morning trading.

Still, analysts continue to worry about how a general slowdown in China could rattle Alibaba. Slower growth is expected to hit the wallets of the Chinese middle class, who regularly splurge on the company’s online shopping platforms. At around $79, Alibaba’s shares are still a long way from the $119 high-water mark they hit after the I.P.O.

“Economic challenges most likely weighed on average spending by buyers,” the research group Trefis wrote in a report.

Speaking to concerns about the Chinese economy, Joe Tsai, the company’s executive vice chairman, said in a conference call on Tuesday that the company did not believe that a blip in Chinese growth would have a long-term impact on the consumer spending on Alibaba’s sites.

“When you look at the Chinese consumer, they’re very liquid. They have lots of cash deposits in their account,” he said, adding “a temporary setback in the macro economy is not going to affect their consumption pattern in a fundamental way.”

In particular, Mr. Tsai noted that Chinese consumption as a percentage of the country’s output is still well below that of developed countries. He expected consumption to naturally become a larger part of China’s economic growth. It is a shift that officials in Beijing are similarly pushing.

Like many Internet players, Alibaba is looking to mobile as it charts out opportunities.

The company’s revenue from mobile advertising, traditionally less than is made on online desktop ads, almost tripled from a year earlier, to $1.7 billion. Alibaba said on Tuesday that mobile phones also account for about 62 percent of the total transactions on its e-commerce sites.

In the conference call, Alibaba executives emphasized new revenue streams that could eventually contribute to the company, including takeout and grocery delivery, a cloud computing unit that serves small businesses, and outreach to rural users.

“Today if you look at the landscape in China, online shopping only accounts for 10 percent of total retail in China,” said Alibaba’s new chief executive, Daniel Zhang. “So I would say that is a huge potential, and if we look at people’s geographic spread, half of our population in the low-tier cities and rural areas, that’s why we initiate our rural program.”

Alibaba’s investment strategy is expected to follow this pattern. This month, Alibaba continued its acquisition streak by making an offer to buy the remainder of a Chinese online video site, Youku Tudou.

“Consumption isn’t just about online shopping, but consumption of digital goods; it’s about consumption of services. We are looking at things that will enhance our position in the consumption economy,” Mr. Tsai said.
