Abstract: Taking into account the situation of natural resources and environment in Jiangsu Province from 1999 to 2010, the losses of the resources and the environment, and green GDP of the province in value were measured and calculated. It was held that its loss of natural resources in value increased in the recent 12 years, reaching 3 097 165.6 million Yuan in total, and its economic development became more and more dependent on natural resources, especially energy; the total loss of environment caused by pollution reached to 93 911 million Yuan in value, showing a fluctuant rising trend on the whole and the environment would go on suffering damage; and its green GDP increased from 658 937 million Yuan in 1999 to 3 626 814 million Yuan in 2010, which accounted for 86.65%, on average, of the traditional GDP annually during the 12 years, and the total cumulative green GDP of the 12 years reached 20 633 450 million Yuan. Meanwhile, its losses of natural resources caused by consumption and losses of environment caused by pollution began to decline in terms of percentage of the GDP, and dropped by 1.414 and 0.26 percentage point, respectively, in the 12 years, while its green GDP gradually increased in terms of percentage of the GDP, too, and rose by 1.95percentage point in the past 12 years. Generally speaking, economic growth reduces the negative externalities of social resources and environment, and embodies structural benefits.
