Indices and Index

Since 1981, the ISPF has been responsible for the calculation of the Consumer Price Index (CPI), which is the instrument for measuring inflation in French Polynesia. This official statistical indicator reflects the increase, fall or stability of prices from one month to another, or over 12 slippery months. It is used as a reference index when reviewing contracts (rents, maintenance, etc.) and to fix the amount of the SMIG. Its calculation is standardised and comes from the collection of numerous prices of products and services, of constant quality, in the territory. Hybrid indexes are linear compositions of elementary indices derived from the consumer price index and/or building and public works indexes. In some cases, the basic indices are complemented by very specific collections to monitor significant budget items not otherwise represented. Since 1981, the ISPF has been responsible for calculating the construction indexes, which reflect the evolution of the burden on construction companies and are used in the revision and updating of public procurement prices. Their calculation is based on the combination of the prices of different types of goods and services according to the division of burdens on an activity. These charges are divided into four major sub-assemblies: — wage and social charges; — energy-related loads; — loads related to the building materials used; — charges related to miscellaneous operating products and services.自1981年起，法国波利尼西亚统计与经济研究所（ISPF）便负责计算消费者物价指数（CPI, Consumer Price Index）——该指数是法属波利尼西亚境内衡量通货膨胀的核心工具。这一官方统计指标可反映月度间及连续12个月度周期内的物价涨跌与平稳态势。其作为合同修订（租金、维保等）的参考基准，同时用于确定跨行业增长最低工资（SMIG）的标准额度。该指数的计算遵循标准化流程，依托法属波利尼西亚境内各类恒定品质的商品与服务价格采集工作完成。 混合指数是由消费者物价指数及/或建筑与公共工程指数衍生出的基础指数经线性组合得到的统计产物。在部分场景中，基础指数会补充纳入专项采集的价格数据，以覆盖未被常规统计体系纳入的重要预算支出项目。 自1981年起，法国波利尼西亚统计与经济研究所（ISPF）同时负责计算建筑工程指数，该指数可反映建筑企业的成本负担变化情况，用于公共采购价格的修订与更新。该类指数的计算基于不同类型商品与服务的价格，并结合建筑活动的成本负担构成进行组合。此类成本负担可划分为四大核心板块： — 工资与社会福利成本； — 能源相关成本； — 所用建筑材料相关成本； — 其他杂项运营产品与服务相关成本。
