3.Input-Output Tables of Subdivided Construction Sectors

Release date:

Every five years

Publicizing Organization:

Construction Research and Statistics office, Policy Bureau
Ministry of Land, Infrastructure, Transport and Tourism (MLIT)

Creation Method

The Input-output Tables of Subdivided Construction Sectors are created using the following data: survey results from the "Input Survey of Building Expenses," "Input Survey of Public Construction Work," "Input Survey of Civil Engineering Work," for different types of construction, and the "Input-output Tables" which are the result of cooperative efforts of 11 ministries and agencies.

1.Key points of the Tables

1) The trading relationships are made clear for each industry

Each industry buys products from other industries as raw materials and adds value to them and produces its own products. In turn, each industry sells its own products to other industries and exports them. The relationships can be understood for all industries by each industry.

2) Grasp on the breakdown of construction cost

For different construction types, it is possible to grasp the breakdown of total costs: labor, materials, design fee, utilities, and so on.

3) Measurements of economic effects

The measurement of production ripple effects to other industries from public investments, capital investments, and housing investments are possible, to begin with. Furthermore, in the same manner, measurements of the effects of regional development investments, large-scale projects, and various events are possible. At the same time, it is possible to measure the effects of these on imports and exports.

4) Application to various analyses

With the use of tables, it is possible to conduct analyses on the effects of changes in the foreign exchange rate of the yen, import prices, and prices for utilities. At the same time, it is possible to conduct analyses of the effects of inflation and deflation on the commodities of various industries.

2.Points to be noted on the use of Tables

1) Since the Tables are created every five years, they reflect the economic structure of the year for which the data were collected. Therefore, when making analyses based on the Tables, the latest table should be used as much as possible.

2) There are several sectors treated specially in the Input-Output Tables, such as the "attribute rent," "self-transport," and "office supplies." It would be desirable to have an understanding of these beforehand.

3) Input-Output Tables are produced by several organizations. Also, the same organization produces several of these tables.
They all differ in concepts and settings of industrial areas. Therefore, when conducting analyses across different tables, it is necessary to use same sector classification tables.

3.Definition of terms

1) Purchasers’prices and Producers’prices

As for individual prices of raw material commodities procured by each industry, the Purchasers’ Price Tables indicates prices that include distribution margins (trade margins and transportation fees). On the other hand, the Producers’Price Tables indicates the prices in shipment price bases, without the distribution margin.

2) Transaction Tables

Transaction Tables indicate the commodity transaction relationships among various industries for transaction amounts. Thus, they are the most basic in the Input-Output Tables. With these tables as a basis, various other tables used in the Input-Output Tables are produced.

3) Input Coefficients Tables (Direct Requirements Tables)

These tables present coefficients for the composition of materials from each industry those are necessary to produce one unit of product in the given industry.

4) Inverse Matrix Coefficients Tables (Total Requirements Tables)

When one unit of demand arises for one industry, the Inverse Matrix Coefficients Tables not only indicate the "amount of materials directly needed" to produce the product, but also the compound material amounts needed by multiple industries or the "material needed to produce the raw material," which is an indirect amount.

5) Production Inducement Coefficients Tables

4.Comparison with other statistics

1) Comparison with Input-Output Tables produced by cooperation among ministries and agencies

As far as the "Input-Output Tables for Analyzing Construction Sectors" are concerned, on the basis of basic sector classification (411 columns x 527 rows) of the Input-Output Tables by cooperation among 9 ministries and 2 agencies and on the basis of 91 sector classifications (Major Group :91 columns x 91 rows), everything is in accord.However, we also produce the MLIT's own aggregated sector classification table (Special Sector Classification) which is 62 columns x 62 rows.In all of these tables, however, 68 construction sectors are set in the construction sectors.

2) Other "Input-Output Tables" produced by MLIT

In addition to the above "Input-Output Tables for Analyzing Construction Sectors," the MLIT produces the "Updated Input-Output Tables for Analyzing Construction Sectors" and the "Inter-Regional Input-Output Tables for Analyzing Construction Sectors."

"Updated Input-Output Tables for Analyzing Construction Sectors" have as their subject years intervening years of the five-year period used in creating the "Input-Output Tables for Analyzing Construction Sectors," and they are also created every five years.
The "Inter-Regional Tables for Analyzing Construction Sectors " are created for the same year as the "Input-Output Tables for Analyzing Construction Sectors," but they focus on regions. Therefore, the tables are quite different in that they take up inter-exchanges among industries in different regions and have different settings.
