This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is a steel pole, which is a transmission steel tube structure composed of single or multiple steel tube members rigidly connected, with a single-piece weight of about 4000 kg, mainly composed of steel plate, round steel, flanges and welding materials, etc., made through processes such as processing, welding and inspection. The key upstream raw materials of this product are steel plate, round steel, steel and flanges, welding materials, etc., and downstream it is mainly applied in fields such as power, communication, municipal and construction, used to form power facility structures and other supporting and transmission structures. In terms of system boundary, infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources, and electricity and other energy are calculated using the Chinese average energy structure.
