Industrial parks have played a key role in promoting economic development around the world. However, rapid industrial park development has resulted in many challenges, including resource depletion, environmental emissions and increasing pressure for industries to respond to climate change. Under such circumstance, a solution to optimize resource utilization and reduce environmental impact is needed. One effective approach is to adopt an eco-industrial development strategy that not only contributes to economic profit and resource conservation, but also to greenhouse gas (GHG) emissions mitigation and environmental service. Such integrated benefits are often termed as co-benefits. However, at present, how to account for such co-benefits at the scale of an eco-industrial park (EIP) is still at an early stage. Therefore, this study aims to evaluate the cobenefits resulting from eco-industrial development and demonstrate how an emergy accounting-based approach can be applied. A case study involving the Dalian Economic and Technological Development Zone (DETDZ) was completed to verify the applicability of this approach. The results indicate that co-benefits go far beyond simple direct economic benefits. The policy implications of such strategies and the application beyond industrial development such as urban symbiosis are discussed within the context of the DETDZ demonstrating how multiple objectives can be achieved.
5. Policy implication and conclusion
Compared with similar industrial structure of industrial parks in northeastern regions in China, DETDZ is a pioneer in the field of energy saving. However, compared to other industrial parks in the developed regions like Tianjin, Guangzhou etc, it is a challenge for the DETDZ to meet similar levels of energy consumption to its nature as a heavy industrial based industrial park. For instance, in 2011, energy consumption per 10 thousand Chinese yuan GDP and water consumption per 10 thousand Chinese yuan GDP in DETDZ were lower than other regions like Northeast regions as well as lower than national average level. However, when compared to Tianjin Economic Development area (TEDA) and Guangzhou industrial park, energy consumption and water consumption for unit GDP generation were higher. The main reason of this was because the main industries in TEDA were electronic communication, vehicle equipment, medical industrial and food industry, while the industrial structure of Guangzhou industrial park was electronic communication, food industry and metal processing. Under such circumstance, DETDZ should promote the eco-industrial efficiency of its industries. DETDZ should also take advantage of its transportation advantage to establish urban symbiosis network among the adjacent regions so that much more cobenefits can be realized in a bigger area.
