The Private Participation in Infrastructure (PPI) Database records contractual arrangements for public infrastructure projects in low- and middle-income countries (as classified by the World Bank) that have reached financial closure, in which private parties assume operating risk. Investment in energy projects with private participation refers to commitments to infrastructure projects in energy (electricity and natural gas: generation, transmission and distribution) that have reached financial closure and directly or indirectly serve the public. The types of projects included are management and lease contracts, brownfield projects, greenfield projects (in which a private entity or a public-private joint venture builds and operates a new facility), and divestitures. Investments are classified as one of two types: (1) Investments in physical assets: resources the project company commits to invest in expanding and modernizing facilities and (2) payments to the government: to acquire state-owned enterprises or rights to provide services in a specific area or to use radio spectrum. Data is presented based on investment year. Data are in current U.S. dollars.
可供参考的中文翻译:私营部门参与的能源投资项目涵盖已进入财务结算阶段,并且直接或间接地为公众提供服务的能源基础设施项目(电力和天然气的发电、输电和配送)。动产与小型项目(如风车)不在此类。包括的项目类型为经营管理合同、有重大资本支出的经营管理合同、新建项目(由私企或公私合资企业建造和运营一个新设施)和资产剥离项目。投资承诺是指设施投资与政府资产投资之和。设施投资是指项目公司承诺在合同期内投入新设施或现有设施扩建和现代化改造的资源。政府资产投资是指项目公司为获取政府资产(国有企业、在特定区域提供服务的权利或特定无线电频谱的使用权等)所投入的资源。数据按现价美元计。

当前构建中,越南最新有值年份为 - 年,最新年份有值指标数为 0,覆盖年份范围为 --- 年,数据总体缺失率约 0%。这意味着不同指标的可用年份并不完全一致,下载长面板后需要先检查缺失值再设定样本区间。
越南 WDI 数据适合用于宏观经济描述、国家画像、时间序列趋势、跨国比较和变量筛选。若用于回归分析,应优先统一年份、单位和价格口径,并记录数据下载日期;若用于课堂报告,可以围绕一组核心变量解释越南与全球或同地区国家的差异。
该页面对应国家样本,可用于与其他国家进行横向比较。 WDI 会随来源机构修订历史数据,且现价美元、购买力平价、不变价、本币、百分比和人均口径含义不同。正式引用时不要只看数值大小,还要核对指标定义、单位、最新更新时间和来源机构。
