Length of Railways in Operation refers to the total length of the trunk line under pass enger and freight transportation
(including bot h full operation and temporary operation). The calculation is based on the actual length of the first line even if
this line has a full or partial double track or more tracks, excluding double tracks, station sidings, tracks under the charge of
stations, branch lines, special-purpose lines and the non-payable connecting lines. The length of railways in operat ion is an
important indicat or to show the development of the infrastructure for the railway transport, and also the essent ial data to
calculate volume of passenger freight transport , traffic density and utilization efficiency of the locomot ives and carriages.

Length of Electrified Railways refers to the length of the section of railways in operation in which the power supply lines
and other equipment are installed for the running of electrified locomotives . The proportion of the length of electrified
railways to the total length of railways in operation is an important indicator to show the modernization of railways.

Automati c-bl ocking and Semi -automati c-bl ocking Length of Railways refer t o length of railways installed with
equipment to perform automatic or manual blocking of trains. Blocking is a spacing technique by which a section of the
railway only allows one train to pass at a time in the aim of ensuring the traffic safety. the proportion of automatic/semi
-automatic blocking length to the total length of railways in operation is an important indicator t o show the modernizat ion of
railways.

Length of Highways refers to the length of highways which are built in conformity with the grades specified by the highway
engineering standard formulated by the Ministry of Communications, and have been formally checked and accep ted by t he
departments of highways and put into use. The lengt h of highways includes that of t he suburb highways at large and
mediumsized cities, highways passing through streets at small cit ies and towns , and also t he length of bridges and ferries.
It does not include the length of s treets in big and medium-sized cities and highways built for t he production purpose at
factories, mines, forest areas and agricultural areas. If two or more highways go the same sect ion of the way, the lengt h of
the section is only calculated for once and no duplication is allowed. The lengt h of highways is an important indicator t o show
the development of the highway cons truction and to provide essential information to calculate the t ransport network density.

Length of Navigable Inland Waterways it is an indicator reflecting the siz e and development of inland water network, it
refers to the length of the natural rivers, lakes , reservoirs, canals, and ditches open to navigation during a given period,
which enables the transport by ships and rafts . It includes the channels open t o navigation for over an accumulative 3
months in a year, yet this does not include the river courses, which are only used to float odd logs and bamboo rafts. This
indicator can reflect the scale, level and development situat ion of the inland waterway network.

Length of Civil Aviation Routes refers to the length of all routes for regular civil aviation flights. There are usually two
ways to calculat e the distance between airports connected by the route length: One is to put the length of all air routes
together, called duplicated calculation of t he length of the routes; the other is not to allow the duplicat ion in calculat ion
when two or more routes passing the same section of aviation routes. The latter is usually used, as it can precisely show the
size of the civil aviation network and indicate the extent of civil aviation serving the national economy and the p eople.

Length of Oil (Gas) Pipelines used as an indicator to show t he development, scale and level of the pipeline
transportation, it refers to t he actual t ransport distance of oil (or gas) products, and is in general calculated in the length of
single pipeline. If the length of the double pipelines and alternate pipeline are included, it is called the extension length of
the oil (gas) pipelines, which indicat es the act ual length of the pip elines built, excluding double pip elines.

Freight (Passenger) Traffic refers to the volume of freight (passenger) transported with various means. Freight t ransport
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 t he act ual weight of t he goods: and despite the traveling dist ance and ticket
price, t he pas senger traffic is calculated by the principle that one person can be counted only once in one travel. The pas
sengers who travel with a half price ticket or a child ticket is also calculated as one person. The freight (pas senger) traffic
provides a quant itative measure t o show how t he transp ort indus try serves t he national economy and people, and is also
an important indicator for planning the t ransport indus try and for s tudying the development scale and speed of the
transport industry.

Freight (Passenger) Traffic Density refers to the freight (passenger) traffic volume carried by a particular means of
transport ation during a given period through one kilomet er of a specific section of transportation route. The formula is as
follows:

Freight (Passenger) Traffic Density =[Freight Ton-kilometers (Passenger-kilometers )] / (Length of Rout e in Operation)

Measuring unit: ton-kilometer / kilometer (or person-kilometer / kilometer)

Freight (pass enger) traffic densit y reflects the degree of business of freight (passenger) traffic on transportation routes, and
therefore provides important information for balancing transport cap ability, planning const ruction and up grading of transport
routes and studying t he distribution of transport network.

Freight Ton-kilometers (Passenger-kilometers) refer to the sum of the p roducts of the volume of transported cargo
(passengers) multiply ing by the transport distance. It is an important indicator to reflect the achievement of t ransportation
indus try. Normally, the shortes t dis tance between the departure stat ion and the destination station (i.e., the payable
distance) is the basis to calculate the freight ton-kilometers. This is an import ant indicator to show the total results of the
transport industry, t o prepare and examine the t ransport p lan and t o measure the efficiency, the labour product ivity and t
he unit cost of transport. The formula is as follows:

Freight Ton-kilometers (Passenger-kilometers) =∑{Freight
(Pass enger) Traffic x Dis tance of Transportation}
Measuring unit: ton-kilometer (person-kilometer)

Static Load of Freight Cars refers t o the average cargo weight as loaded by each freight car under the static condition at
the dep arture station. It is used to show the utilization extent of the loading capacity of the freight cars . The formula is:

Static Load (t on) of Freight Car= (Tonnage of Goods Dispatched) / (Number of Freight Cars Loaded)

The static load of freight cars is determined by the nature and type of goods loaded, the type of vehicles, and the technique
of loading. The difference between the average marked load and the stat ic load of freight cars reflects the utilization of
loading capacity of freight cars. For its calculat ion the following formula is app lied:

Utilization Rat e of Capacity of Freight Cars(%)=[(Average Static Load)× 100%] / (Average Marked Load)

Average Daily Haul of Freight Locomotives refers to the average total ton-kilometers accomplished by each freight
transport locomotive over day and night during a given period of time. It includes both the weight of t he goods carried and
the dead weight of the train itself. It is a comp rehensive indicator reflecting the locomotive efficiency in terms of both time
and the pulling force.

Average Daily Haul of Freight Transport Locomotive (tonkilometer)=[( Total Ton/(Kilomet ers of Freight)] / (Daily Number
of Freight Transport Locomotive)

Volume of Freight Handled in Major Coastal Ports refers t o the volume of cargo passing in and out the harbor area of
the major coas tal port s and having been loaded and unloaded. The volume includes that of t he postal matters, registered
luggage and fuels, materials and fresh water as supplies of the ships. The volume of freight handled may be classified by
direction of flow as freight for import and freight for export , or by nat ure of cargo as freight for domestic trade and freight
for foreign trade. As an important indicator, the volume of freight handled by type of cargo and by main flow direction reflects
the production capacity of ports.

Posses sion of Civi l Motor Vehi cles : refer t o t he tot al numbers of vehicles t hat are regis tered and received
vehicles' license tags according to t he Work Standard for Motor Vehicles Registrat ion formulat ed by transp ort management
office under department of public s ecurity 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 t o ownerships; working vehicles, non-working vehicles and special motor vehicles according to kind of usage; large
passenger vehicles, medium pass enger vehicles and small pass enger vehicles, heavy trucks, light -heavy t rucks and light
trucks according to sizes of vehicles.

Busine ss Volume of Post and Telecommunications refers to the total amount of post and telecommunication s
ervices, expres sed in value terms, provided by the post and telecommunications departments for the societ y. Post and
telecommunication services can be classified as letters, parcels, remittance, issue of newspap ers and magazines, fas t mail
service, expres s mail service, savings deposits, s tamps 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) t o get sum of business value, plus income from other services such as leas ing of telephone lines and
equipment , maintenance of t elep hone swit chboards and lines on behalf of customers . This indicat or reflects the overall
results of post and t elecommunications service during a given p eriod, and is important to s tudy the composit ion of
business service and the development of post and telecommunications service. The formula is as follows:

Busines s Volume of Pos t and Telecommunications= ∑
(Transaction of Pos t and Telecommunication Service x Constant
Price) + Income from Leas ing, Maint enance and other Services

Subscribers of Wireless Paging Services Wireless paging s ervice refers the service by which t elephone users send
audio, digit al or character signals to persons carrying small-size pagers within the designated areas through wireless paging
centers. The page carriers who have regis tered in paging centers are count ed as paging subscribers.

Mobil e Telephone Subscribers refer to the persons who own mobile telephone numbers and are connected with the
mobile telephone communication network through the mobile telephone swit chboards, including cont racted subscribers and p
repaid subscribers for intelligent network. One mobile t elephone is taken as a subscriber.

Local Telephone Subscribers refer to subscribers t hat are connect ed to the local t elecommunicat ion s ervice p rovider
through fix line network, including household subscribers, institutional subscribers and public telephones. They are also
classified as city subs cribers and rural subscribers according to locations. Before 1997, city subscribers referred to those
connected to cit y telephone networks in county t owns and cit ies, while village subscribers referred to thos e connected to
village telephone s tations at and below count ies. Since 1997, the clas sification of telephone subscribers was modified on
the basis of physical location of the subscribers as urban telephone subscribers and rural t elephone subscribers , which is
different from t he previous classification of categorizing local telephones and rural telephones , while the definit ion of total
subscribers and total number of telephones remain unchanged.

Urban Telephone Subscribers refer to number of telephone subscribers , located at municipalities, cit ies under t he
jurisdiction of province, cities at prefecture level, downtown and suburb of city at county level t own and county towns (including
count ry towns where count y government located, and towns of count y level according to the administrat ive organizational
system), that are connect ed t o the public line t elephone network, including rural mineral area, forest area, military area.

Rural Telephone Subscribers refer to telephone subscribers, located at counties (towns) and villages out side the range
of cities according to administrative jurisdiction.

Household Telephone Subscribers refer to telephone sets installed in the dwelling units of urban or rural resident s, and
registered as residence subscribers for payment, including 3 types of payment for t he service: privat e payment , public
payment and free service.
