Explanatory Notes on Main Statistical Indicators

 

Freight (Passenger) Traffic   refers to the volume of freight (passenger) transported with various means. Freight transport is calculated in tons and passenger traffic is calculated in the number of persons. Despite the type of freight and traveling distance, the freight transport is calculated in the actual weight of the goods; and despite the traveling distance and ticket price, the passenger traffic is calculated by the principle that one person can be counted only once in one travel. The passenger who travels with a half-price ticket or a child ticket is also calculated as one person. The freight (passenger) traffic provides a quantitative measure to show how the transport industry serves the national economy and people, and is also an important indicator for planning the transport industry and for studying the development scale and speed of the transport industry.

Freight Ton-kilometers (Passenger-kilometers)   refer to the sum of the products of the volume of transported cargo (passengers) multiplying by the transport distance. It is an important indicator to reflect the achievement of transportation industry. Normally, the shortest distance between the departure station and the destination station (i.e., the payable distance) is the basis to calculate the freight ton-kilometers. This is an important indicator to show the total results of the transport industry, to prepare and examine the transport plan and to measure the efficiency, the labour productivity and the unit cost of transport. The formula is as follows:

Freight Ton-kilometers (Passenger-Kilometers) = ¡Æ [Freight (Passenger) Traffic ¡Á Distance of Transportation]

Length of Highways   refers to the actual length of highways at the end of reference period. It covers public roads running vehicles among cities, city and rural areas, township (villages), highways passing through streets at small cities and towns, length of bridges and tunnels, width of ferry piers. It does not include the length of streets in cities, dead end highways, the length of streets built for agricultural (forest) production and inside factories (mines). It can only be calculated with the actual mileage having been completed, checked and accepted or put into operation. If two or more highways go the same section of the way, the length of the section is only calculated for once.

Length of Navigable Inland Waterways   refers to the length of natural rivers, lakes, reservoirs and canals that are open to navigation for ships and rafts during a given period. It includes the channels with annual seasonal navigation for more than three months other than the waterways only for scattered bamboo and wooden rafts. If two provinces share one river as the border, the length of waterways will be half divided for each province to avoid duplication.

Possession of Civil Motor Vehicles   refer to the total numbers of vehicles that are registered and received vehicles¡¯ license tags according to the Work Standard for Motor Vehicles Registration formulated by transport management office under department of public security at the end of reference period. They are divided into following categories according to the structure of motor vehicles: passenger vehicles, trucks and others; and private vehicles and vehicles for units use according to ownerships; working vehicles, non-working vehicles and special motor vehicles according to kind of usage; large passenger vehicles, medium passenger vehicles and small passenger vehicles, heavy trucks, light-heavy trucks and light trucks according to sizes of vehicles.

Business Volume of Post and Telecommunications   refers to the total amount of postal and telecommunication services, expressed in value terms, provided by the post and telecommunications departments for society. Business volume of post and telecommunications is the sum of each service in kind multiplying with its correspondent unit price (constant price). Business without constant price add their business revenue directly.

Business Volume of Postal and Telecommunication Services = ¡Æ (Transaction of Post and Telecommunication Services ¡Á Constant Price) + Income from Leasing, Maintenance and other Services = Business Volume of Postal Services + Business Volume of Telecommunication Services

Local Telephone Subscribers   refer to all subscribers who have gone through registration procedures in the operation points of enterprises engaged in telecommunications and are hence connected to the local telecommunications service provider through fixed line network. Included are general subscribers, wireless local telephone subscribers, public telephones subscribers, N-ISDN subscribers and intelligent network terminal subscribers.

Urban Telephone Subscribers   refer to subscribers telephone subscribers, located at municipalities, cities under the jurisdiction of province, cities at prefectural level, downtown and suburb of city at county level town and county towns (including country towns where county government located, and towns of county level according to the administrative organizational system), that are connected to the public line telephone network, including rural mineral area, forest area, military area.

Rural Telephone Subscribers   refer to telephone subscribers, located at the towns and villages outside the coverage of urban areas according to the administrative division.

Mobile Telephone Subscribers   refer to persons who have gone through registration procedures in the operation points of enterprises engaged in telecommunications and are hence connected with the mobile telephone communication network through the mobile telephone switchboards and occupy mobile phone numbers. Included are various types of subscriber, prepaid users for intelligent network and wireless network card users.

Capacity of Office Telephone Exchanges   refers to the capacity (measured in gate) of telephone exchanges installed in the offices of telecommunication service providers for communication between fixed telephones. It includes the capacity of access network equipment (capacity of equipment installed in the offices of telecommunication service providers for connecting distant nodes of voice users).

Capacity of Mobile Telephone Exchanges   refers to the capacity of the maximum services provided to subscribers at any one time as computed based on a certain model of calls distribution and transacting capacity of the mobile telephone exchanges. It is calculated based on the actual capacity of equipments connected to network through cutover and put into operation officially at the end of the reference period.

Length of Railways in Operation   refers to the total length of the trunk line for passenger and freight transportation in full operation or temporary operation.

Length of Electrified Trunk Line   refers to the length of the trunk line capable for the running of electrified locomotives and having been put into operation.

Length of Routes with Scheduled Flights   refers to the total length of all routes for scheduled flights, which is calculated using million kilometres as the unit. There are usually two ways to calculate the route length: duplicated calculation and non-duplicated calculation. Duplicated calculation means that the same segment of different routes can be added duplicately, while the non-duplicated calculation allows the same segment of different routes be counted once only.

Length of Oil (Gas) Pipelines   refers to the actual transport distance of oil, gas and oil products, an indicator reflecting the length of transportation routes and a reference to calculate the freight-kilometers. For those sections with double pipelines and alternate pipeline, the length will be calculated according to the length of single pipeline in principle. If the double pipelines perform the transportation at the same time and unable to be counted separately, the length of pipelines will be the length of double pipelines divided by 2.

Volume of Freight Handled in Coastal Ports   refers to the volume of cargo passing in and out of the harbour area of the major coastal ports and having been loaded and unloaded. The volume of freight handled may be classified by direction of cargo flow as in-port freight and out-port freight, or by nature of cargo as freight for domestic trade and freight for foreign trade. It can also be classified by type of freight based on the existing standard classification for transportation industry ¡°Classification and Coding for Freight¡±.

Possession of Civil Transport Vessels   refers to the total number at the end of reference period of operating transport vessels owned by Chinese enterprises or privately that are registered in the water transportation management institutions and permitted to perform cargo transport activities (including vessels with foreign flags but owned by Chinese enterprises or citizens). Non-transport vessels and vessels used for agriculture and fishery are not included.

Internet Users   refer to the number of Chinese citizens aged 6 and over who use the Internet in the past six months.

Capacity of Long Distance Telephone Exchanges   refers to the rated capacity of telephone exchanges to connect long distance telephone network by enterprises engaged in telecommunications.

Broadband Connection Terminals   refer to the connection terminals to internet users actually installed and put into operation, including connection terminals for XDSL, connection terminals for LAN, and other types of connection terminals. N-ISDN connection terminals are not included.
