The National Development and Reform Commission (NDRC) also warned local governments not to violate laws, regulations and policies by introducing preferential policies such as tax cuts to attract new high energy-consuming projects in the future.
The NDRC said local governments should set stricter market access standards to help eliminate outdated production facilities and tighten land use and credit supply for new projects.
To slow down the rapid growth of high energy-consuming projects is crucial to meeting China's energy saving and pollution reduction targets, the NDRC said in a statement on its Website.
The Chinese government has set a goal of reducing energy consumption per unit of gross domestic product by 20 percent by 2010, while pollutant discharge should drop by 10 percent.
Energy consumption, however, fell only 1.23 percent last year, less than one third of the annual goal of four percent.
Most of the energy-gorging industries including steel, electrolytic aluminum and cement saw growth rebound in the first quarter of the year after China introduced cooling measures in 2003, said the NDRC.
The six sectors of power, steel, oil refinery, chemicals, construction materials, and metals consume 70 percent of energy for industry and release the same percentage of sulfur dioxide.
The output of these sectors grew 20.6 percent in the first quarter, 6.6 percentage points higher than the same period last year, Chinese Premier Wen Jiabao said earlier this month.
Wen pledged China would push forward reforms in the pricing of natural gas, water and other resources, raise the tax levied on pollutant discharge, establish a "polluter pays" system and severely punish those who violate the environmental protection laws.
The premier said the economy could hardly be sustainable if China failed to adjust the economic structure, transform the growth mode, and reduce energy consumption.
At 0200 EST (0700 GMT) clocks moved forward by an hour, shifting an hour of daylight from morning to evening.
Summer time will last until 4 November, a week later than in previous years.
The extra four weeks are expected to help cut energy consumption, as demand falls for electricity in the evening if it is still light.
The measure was signed into law in two years ago as part of the Energy Policy Act which aims to encourage new energy technologies.
Representatives Edward Markey and Fred Upton, who sponsored the amendment to the original bill, said it was expected to save $4.4bn in energy bills by 2020 and avoid the need to build more than three large electric power plants.
They said it also would save 279 billion cubic feet of natural gas, and avoid nearly 10.8 million metric tons of carbon emissions.
"The change in the beginning of daylight saving time is just one step towards making our country more efficient in its usage of energy and conscious of our environment," Mr Markey said on Wednesday.
"Not only will Americans have more daylight at their disposal for four additional weeks in the year, but we will also see wide energy saving, less crime, fewer traffic fatalities, more recreation time and increased economic activity.
"Ultimately, daylight saving just brings a smile to everybody's faces."
Critics of the measure say the early switch may potentially lead to computer failures and cause minor headaches such as electronic calendars being out of synch, leading to missed appointments.
Canada also advances its clocks this weekend, with all provinces moving forward an hour, except Saskatchewan which does not observe Daylight Saving Time.
