指标解释
World Bank official description / 世界银行官方说明
Net official flows from UN agencies are the net disbursements of total official flows from the UN agencies. Total official flows are the sum of Official Development Assistance (ODA) or official aid and Other Official Flows (OOF) and represent the total disbursements by the official sector at large to the recipient country. Net disbursements are gross disbursements of grants and loans minus repayments of principal on earlier loans. ODA consists of loans made on concessional terms (with a grant element of at least 25 percent, calculated at a rate of discount of 10 percent) and grants made to promote economic development and welfare in countries and territories in the DAC list of ODA recipients. Official aid refers to aid flows from official donors to countries and territories in part II of the DAC list of recipients: more advanced countries of Central and Eastern Europe, the countries of the former Soviet Union, and certain advanced developing countries and territories. Official aid is provided under terms and conditions similar to those for ODA. Part II of the DAC List was abolished in 2005. The collection of data on official aid and other resource flows to Part II countries ended with 2004 data. OOF are transactions by the official sector whose main objective is other than development-motivated, or, if development-motivated, whose grant element is below the 25 per cent threshold which would make them eligible to be recorded as ODA. The main classes of transactions included here are official export credits, official sector equity and portfolio investment, and debt reorganization undertaken by the official sector at nonconcessional terms (irrespective of the nature or the identity of the original creditor). UN agencies are United Nations includes the United Nations Children’s Fund (UNICEF), United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), World Food Programme (WFP), International Fund for Agricultural Development (IFAD), United Nations Development Programme(UNDP), United Nations Population Fund (UNFPA), United Nations Refugee Agency (UNHCR), Joint United Nations Programme on HIV/AIDS (UNAIDS), United Nations Regular Programme for Technical Assistance (UNTA), United Nations Peacebuilding Fund (UNPBF), International Atomic Energy Agency (IAEA), World Health Organization (WHO), United Nations Economic Commission for Europe (UNECE), Food and Agriculture Organization of the United Nations (FAO), International Labour Organization (ILO), United Nations Environment Programme (UNEP), World Tourism Organization (UNWTO) and United Nations Institute for Disarmament Research (UNIDIR). Data are in current U.S. dollars.
可供参考的中文翻译：来自联合国机构的净官方流量是来自联合国机构官方流量总额的净支付额。官方流动总额是官方发展援助（ODA）或官方援助和其他官方流动（OOF）的总和，代表整个官方部门向受援国提供的支付总额。净支付是赠款和贷款的支付总额减去偿还以往贷款的本金。官方发展援助（ODA）包括以优惠条件提供的贷款（至少具有25%的捐赠成分，以10%的贴现率计算）和旨在促进经济发展和福祉的赠款。官方援助指的是官方捐助者为较先进的中东欧国家、前苏联国家以及某些先进的发展中国家和领地提供的援助。UNDP是联合国开发计划署，是联合国系统内专注于发展领域的主要机构。数据按现价美元计。
数据口径与风险提示
- 本指标记录的是联合国开发计划署（UNDP）对各国的净支付额，净值为正时表示流入，负值时表示流出，不能简单以数值高低评判发展成效。
- UNDP资金覆盖发展项目的多个领域，包括减贫治理、能力建设、技术援助等，指标数值本身无法区分资金的具体用途方向。
- 现价美元口径未剔除通货膨胀影响，跨年比较时需考虑美元购买力变化，尤其是1980年代至1990年代的高通胀时期。
- 中国数据起始于1979年，1980年前后的数据不可比；世界数据在2023年归零可能反映统计报告周期或数据可得性问题，而非实际资金完全终止。
- UNDP资金结构包含赠款和优惠贷款，净支付额受项目周期和还款节奏影响，短期波动不必然反映援助政策实质变化。
- 负值表示该年度 UNDP 从某国的回收或偿还金额超过新拨付额，这属于正常资金运作现象，不代表双边关系恶化。
萨摩亚WDI数据常见问题
数据覆盖如何理解？
当前构建中，萨摩亚最新有值年份为 - 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。
论文和课程作业怎么用？
萨摩亚 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萨摩亚与全球或同地区国家的差异。
有哪些使用风险？
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。
