Explanatory Notes on Main Statistical Indicators
Freight
(Passenger) Traffic
refers to the volume of freight (passenger) transported with various means
within a specific period of time. This indicator reflects the service of the
transport industry towards the national economy and people��s living conditions,
as well as an important indicator used in formulating and monitoring transport
production plans and research into the scale and pace of transport development.
Freight transport is calculated in tons and passenger traffic is calculated in
terms of number of persons. Freight transport is calculated in terms of the
actual weight of the goods and takes no account of the type of freight and
distance of travel. Passenger traffic is calculated by the principle that one
person can be counted only once in one trip and takes no account of the travelling distance and ticket price. The passengers who
travel with a half price ticket or a child��s ticket is also calculated as one
person.
Turnover
Volume of Freight (Passenger) Traffic
refers to the sum of the product of the volume of transported cargo (passengers) multiplied by the transport distance. It is an important indicator to reflect the achievement of the transportation industry. This is an important indicator to show the total results of the transport industry; to prepare and examine the transport plan; and to serve as the main basic data for calculating the efficiency, labour productivity and unit cost of transport. Normally, the shortest distance between the departure station and the destination station (i.e., the payable distance) is the basis in calculating the freight ton-kilometers. The formula is as followed:
Turnover Volume of Freight (Passenger) Traffic =��(Freight (Passenger) Traffic �� Distance of Transportation)
Freight
Handled in Ports
refers to the volume of cargo passing in and out the harbor area and
having been loaded and unloaded. The volume of freight handled may be
classified as in-port & out-port. It can also be classified as national
trade and international trade by the attribute of trade or be classified by the
classification of cargo according to the standard of traffic in use The
Classification and Code of Transported Cargo.
Container
Handled in Ports
refers to number and weight of containers which are loaded or unloaded
within port area via water carriage. It is often calculated by entering and
leaving port, respectively. TEU was the abbreviation of twenty foot equivalent
unit, which refers to converted number of all kinds of containers. The
conversion method is based on respective conversion ratio and the number of all
kinds of container is converted to the standard number of 20-foot equivalent
unit. The conversion ratio is 40-foot container 1:2, 35-foot container 1:1.75, 20-foot container 1:1, 10-foot container 1:0.5.
Business
Value of Post and Telecommunication Services
refers to the total amount of post and telecommunication services, expressed in value terms, provided by the post and telecommunications departments for the society. Post and telecommunication services can be classified as letters, parcels, remittance, issue of newspapers and magazines, fast mail service, express mail service, savings deposits, stamps for collection, public and individual telegraph service, facsimiles, long-distance telephone service, leasing of telephone lines, urban paging service, mobile telephone service, data transfer and transmission, etc. The accounting approach is to multiply the service products of all types with their average unit price (constant price) to get sum of business value, plus income from other services such as leasing of telephone lines and equipment, maintenance of telephone switchboards and lines on behalf of customers. This indicator reflects the overall results of post and telecommunications service during a given period, and is important to study the composition of business service and the development of post and telecommunications service. The formula is as followed:
Business Value of Post and Telecommunication
Services =
�� (Transaction
of Post and Telecommunication Services �� Constant Price) + Income from leasing, Maintenance and Other
Services = Business Volume of Post + Business Volume of Telecommunication
Civil
Motor Vehicles Owned
refers to the total number 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, small passenger vehicles and mini passenger vehicle, heavy trucks,
light-heavy trucks, light trucks and mini trucks according to sizes of
vehicles.
Capacity
of Office Telephone Exchanges
refers to the capacity of telephone exchanges installed in the local
offices of telecommunication service providers for communication between fixed
telephones. It is includes the capacity of both manual and automatic exchanges
in use and for stand-by purpose and calculated according to the multiplied
capacity if equipped with multiplier equipment.

of
refers to the capacity of the maximum services provided to subscribers at
one time basing on a certain model and transacting capacity of the mobile
telephone exchanges.
