0207. Construction price index

1. Concept, calculation method

The construction price index is a relative indicator (expressed in %) reflecting the degree of change (increase or decrease) in construction prices over time nationwide.

The representative product list is established based on the main building materials of construction works, which are materials occupying a large proportion of material costs, widely used, and relatively stable and long-lasting in construction activities; major construction machinery and equipment are commonly used types with high cost proportions in construction works; major construction workers are common workers with high labor cost proportions in construction works.

The weighting factor for calculating the construction price index is the percentage share of the production value of each group of products in the total production value of construction. The source of the construction production value is collected from competent agencies.

The construction price index is calculated using the weighted average Laspeyres formula as follows:

Where:

: Is the construction price index for the reporting period (t) compared to the fixed base period (0);

, : Corresponding to the construction product price in the reporting period (t) and the fixed base period (0);

: Is the weighting factor for the fixed base period (0);

: Is the construction production value in the fixed base period (0);

n: Is the number of products.

The provincial/city-level construction price index is calculated by averaging the weighted price indices of representative product groups selected for investigation with corresponding weights.

The construction price index for each region is calculated using the weighted arithmetic mean method between the construction price indices of each province/city directly under the central government within the region and their corresponding weights.

The national construction price index is calculated using the weighted arithmetic mean method between the construction price indices of each region and their corresponding weights.

2. Main categories:

Product group: By type of project.

3. Year of publication:Year.

4. Data sources: The calculation to determine the construction price index is based on data and information about material prices, labor costs, and construction machinery published by local authorities according to current regulations on investment cost management.
