In the last ten years especially, while China's economy has boomed, logistics resources owned by companies or individuals have been abundant. However, due to the unbalanced distribution of logistics demands in China and the asymmetry of information, logistics resources and their capacity are not fully utilized. The empty load ratio (ELR) is high, such that transport resources are wasted and the environment is polluted. The ELR is the ratio of mileage without load to total mileage in the context of a full or less-than-full truck load. The ELR commonly measures the efficiency of a route and waste. According to statistics, the ELR in China was low during the planned economy, and was high, almost reaching 50%, during the market economy; with the evolution of logistics requirements, transport capacity, and information technology, the ELR is dropping to roughly 40%. Notably, different vehicle types may have different ELRs (e.g. taxis have lower ELRs than trucks) and different areas with unbalanced logistics requirements and transport capacities have different ELRs. In China, as an economic indicator and environmental indicator, the ELR can be further minimized.
