Investors shouldn't fret over lower growth forecasts for China, economist and senior fellow at Yale University Stephen Roach told CNBC, noting there are no magic numbers when it comes to economic growth.
"[Just] like the Fed [Federal Reserve] is backing away from magic numbers on the U.S., there is no magic number for any economy," said Roach, who previously worked as chairman for Asia at Morgan Stanley.
China's economy is now more geared towards the services industry, which is positive according to Roach as each unit of output in a services-based economy generates 30 percent more jobs than in a manufacturing and construction-based economy.

"What used to take 10 percent of Chinese growth to absorb surplus labor and deal with poverty can now be done at 7 percent. So they can grow much, much more slowly, and still absorb the surplus labor," he added.

Many analysts have turned more bearish on China in recent years, as the government's plan to transition from investment-led growth to more a more consumption-driven economy has slowed the pace of growth from the double digit levels seen in recent decades.
China's economy grew 7.7 percent last year and the government is targeting 7.5 percent this year.
Goldman Sachs lowered its forecast for 2014 to 7.3 percent from a previous projection of 7.6 percent late Wednesday.

The shortage of low-cost workers in recent years has also been a key concern for analysts. In 2013, wages for Chinese migrant workers increased 13.9 percent on year, data from the National Bureau of Statistics showed.
