The study of eco-economic system was important to the formulation of sustainable development strategy. Using the Emergy analysis method, a comprehensive analysis of the Hebei eco-economic system in 2007 was conducted on resource utilization, input and output, environmental load. The results showed that total energy usage was 7.70×1023sej, including the value of non-renewable resources products, renewable environmental resources, imports , exports was 7.42×1023sej , 4.93×1022sej, 5.33×1022sej, 7.41×1022sej, 2.13×1023sej, respectively; the value of renewable resource products was 2.13×1023sej, including the value of agricultural products, animal products, aquatic products was 1.23×1023sej, 6.78×1022sej, 8.37×1021sej, respectively; Emergy self-sufficiency was 105.4%, Emergy yield ratio was 30.3%, energy using density was 4.10×1012sej.m-2, energy usage per capita was 1.11×1016sej.人-1, Emergy currency ratio was 5.62×1011sej.元-1, waste Emergy was 4.66×1021sej, environmental loading ratio was 16.1, sustainable development index was 53.2. To sum up, the eco-economic system was unsustainable development.
