美国相信“学历无用论”的人变多了?

大家好,我是卷卷兔。 即便到了暑假,美国名校依然没能轻松下来。7月28日,《纽约时报》爆出哈佛与老特的旷日持久谈判有了结果:"哈佛愿意斥资高达5亿美元来结束与白/ 宫的争端"。 而这个金额,比此前哥大被罚的2亿美元的两倍还多。 有媒体夸张地说,"一场美国高等教育的坍塌开始,美国大学已经走到尽头"。 德勤也在今年发布了最新的《2025高等教育趋势》报告,也发现美国相信"读大学无用"的人开始变多了: 对学位价值的担忧、政治化、学费上涨以及与劳动力需求的差距,美国民众对高等教育价值的信任度已从2015年的57%下降至2024年的仅 36%,足足减少21%。 意味着约三分之二的美国人,对高等教育的价值产生了怀疑。 然而,即便美国大学被媒体频频唱衰,在这两天谷雨星球美国访校中,我们却看到了和媒体不一样的美国大学。 刚抵达的第一天,我们在大学校园里偶遇了各种鲜活、热情而真实的人,他们似乎从没有受到影响,忙碌着自己的事,更不像报道中所说的"学生开始为 未来担心"。 这里的自由与包容,就像一个天然安全的场域,将外界的风波和舆论挡在了外面。有孩子说,"真正踏足在美国校园里,才理解为什么那么多人来到美国 奔赴高等教育"。 美国人 ...

Core Viewpoint - The recent issuance of the "Notice on the Construction of Zero Carbon Parks" by the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the National Energy Administration marks a significant shift in China's carbon governance approach, moving from individual enterprise emissions reduction to systematic, regional low-carbon transformation [1][4]. Group 1: Policy Framework - The policy document includes one main file and four supporting guidelines, which outline the basic conditions for zero carbon park construction, the application outline for national-level zero carbon parks, a trial indicator system, and carbon emission accounting methods [2]. - The notice establishes construction standards and a management framework for zero carbon parks, with application entities primarily being provincial-level development zones included in the latest "Directory of Approved Development Zones" [2]. - A tiered assessment system is created based on the annual comprehensive energy consumption scale of the parks, categorizing core indicators of unit energy consumption carbon emissions into two tiers [2]. Group 2: Emission Standards - The trial indicator system specifies carbon emission intensity requirements: parks with annual energy consumption of 200,000 to 1,000,000 tons of standard coal must have unit energy consumption carbon emissions ≤0.2 tons/ton of standard coal, while those with consumption ≥1,000,000 tons must meet ≤0.3 tons/ton [2]. - Additional guiding indicators include a clean energy consumption ratio of ≥90%, industrial solid waste comprehensive utilization rate of ≥80%, and waste heat and pressure utilization rate of ≥50% [2]. Group 3: Carbon Accounting - The "Carbon Emission Accounting Method" includes net electricity intake and industrial process emissions in a unified accounting framework, establishing a full lifecycle carbon emission accounting system [3]. - Renewable energy power obtained through green electricity direct supply or green certificate trading is assigned a carbon emission factor of 0, while other electricity is calculated using the national fossil energy power emission factor of 0.8325 kgCO/kWh [3]. - The notice emphasizes that the proportion of electricity supplied directly through green power should not be less than 50% [3]. Group 4: Economic Viability and Financial Support - The shift to park-based management for emissions reduction offers institutional advantages, allowing for the integration of land and policy incentives to encourage enterprise participation [4]. - The construction of zero carbon parks requires economic viability to achieve expected effects, alongside support from policies and financial institutions [4][5]. - The need for green financial support is highlighted, with suggestions for diversified financing models, including the establishment of special funds and the introduction of long-term capital [5]. - Innovative financial products, such as "carbon footprint-linked loans," are being piloted by some commercial banks, linking loan interest rates to the carbon reduction performance of parks [5].
