研究团队通过一系列实验，发现了蓝耳病病毒"作恶"的关键步骤。蓝耳病病毒感染猪肺细胞后会激活一 种特定蛋白，指挥细胞内的"骨架"重新排列，形成特殊的"脚手架"结构，并使得细胞表面的黏附"受 体"数量大增，这些受体就像一个个"登船梯"。有了"脚手架"和"登船梯"，原本难以入侵的细菌得以"搭 便车"侵入，引发严重继发感染。 业内专家认为，这项研究揭示了病毒帮助细菌入侵的分子机制，为开发药物、疫苗或基因编辑等防控策 略提供了新靶点和新思路。（记者古一平） 记者从中国农业科学院获悉，中国农业科学院兰州兽医研究所动物免疫与代谢创新团队，近日研究揭示 了猪在感染蓝耳病病毒后容易引发细菌继发感染的关键机制，为解决这一困扰猪养殖业的世界性难题提 供了新的防控思路和药物靶点。 据介绍，猪感染蓝耳病病毒后，常常会"雪上加霜"，继发各种细菌感染，导致病情急剧恶化，病死率显 著升高，给养猪业造成巨大经济损失。然而，长期以来，业内对蓝耳病病毒如何"帮助"细菌入侵的具体 机制知之甚少。 ...

王毅外长此次欧洲之行传递出明确信息：中国始终敞开对话大门，但绝不会在威胁下让步。中欧关系正 处在关键十字路口，欧洲面临战略抉择：是继续被美国绑架而承受经济损失，还是基于自身利益深化对 华合作。在气候变化、数字经济、绿色能源等新兴领域，中欧合作潜力巨大。据欧盟统计局数据，2022 年中欧贸易额达8563亿欧元，中国连续三年保持欧盟最大贸易伙伴地位。 朋友非对手，合作不对抗不仅是外交辞令，更是中国对欧战略的核心原则。当美国试图用旧式霸权思维 处理国际关系时，中国正通过构建新型国际关系赢得更多合作伙伴。王毅外长此次访问的每个表态、每 场会谈，都在向世界展示：一个坚持原则又开放包容的中国，正在为动荡的世界注入稳定性。欧洲能否 把握历史机遇，将决定其能否在美中博弈中找到最符合自身利益的位置。 回望中欧建交50年历程，双方经贸合作已形成深度互依格局。德国汽车工业30%的销量依赖中国市场， 法国奢侈品牌在华销售额占全球四成，丹麦乳制品出口的25%销往中国。然而在政治层面，欧洲却时常 表现出矛盾立场：一方面积极参与一带一路合作，另一方面又在议会推动各类对华限制法案。这种经济 靠中国、安全靠美国的双轨制策略，正导致欧洲内部工商 ...

齐鲁晚报.齐鲁壹点记者张志恒 "金九银十"本是猪肉消费的传统旺季，叠加中秋国庆双节临近，市场却迎来反常行情。9月16日，记者走访济南部分超市和社区生鲜店看到，猪肉柜台的 价钱标注：筒骨6.88元/斤、后腿肉8.99元/斤、精选肘肉11.8元/斤、带颈前排12.8元/斤......不少买菜的消费者均疑惑，最近猪肉价格又下降了？ 据中国养猪网数据显示，当日全国生猪(外三元)均价跌至13.20元/公斤，同比大跌31.61%，广西等产区甚至跌破6元/斤关口。 农业农村部数据显示，当前全国能繁母猪存栏量达4043万头，超出正常保有量3.7%。迟先生对此深有体会："现在能繁母猪两年能产三胎，每胎仔猪能有 10到20头，繁殖效率比以前高多了。加上养殖技术和防疫能力提升，没了大的疫病影响，毛猪存栏量自然逐步增长。"叠加头部猪企的出栏放量，20家头 部猪企8月合计出栏1684.38万头，18家实现同比正增长，部分甚至翻番。为抢占市场份额，大型企业即便亏损仍维持高出栏量，中小养殖户只能跟风降 价，进一步加剧供应压力。 需求端的低迷则让供需失衡雪上加霜。餐饮行业采购量下滑，居民日常消费与节假日消费均不及往年。"7月放暑假后，普通地 ...

Group 1 - The Chinese government has imposed a preliminary anti-dumping tax of 62.4% on European pork imports, significantly impacting the European pork industry [1][3] - The tax rates vary by country, with Spain at 15.6%, Denmark at 31.3%, and the Netherlands at 32.7%, while non-compliant companies face the full 62.4% [3] - The restriction on pork imports from China, which accounts for a quarter of the EU's pork export market, has led to a surplus of pork in Europe, signaling a potential industry downturn [3][6] Group 2 - European by-products such as pig ears, noses, and offal, which have low local demand, are highly sought after in China, creating a significant market dependency [6] - The increase in tariffs has resulted in a loss of the primary buyer for these by-products, leading to a cash flow crisis for European producers as both primary and secondary products become unsellable [6] - The European stance towards China is characterized by a conflict between following U.S. pressure and the necessity of maintaining access to the Chinese market [8][11] Group 3 - Europe is heavily reliant on China as a major trade partner, particularly in sectors like automotive, machinery, and luxury goods, making the current situation critical for its economy [8] - The U.S. is pressuring Europe to align with its policies against China, which could exacerbate Europe's economic challenges while benefiting U.S. interests [9][11] - The European dilemma involves balancing the need to maintain economic ties with China while managing the geopolitical pressures from the U.S. [11]

Quantitative Models and Construction Methods 1. Model Name: Pring Cycle - **Model Construction Idea**: The Pring Cycle is an upgraded version of the Merrill Clock, incorporating financial data to enhance the predictive accuracy of asset allocation recommendations. It defines financial indicators as leading indicators, real economy indicators as coincident indicators, and price indicators as lagging indicators. These three groups of indicators form six economic states, each corresponding to specific asset allocation strategies [9][10][11] - **Model Construction Process**: 1. Leading indicators include M2 growth and new social financing, filtered for cyclical factors to observe trend components [14] 2. Coincident indicators include real estate investment and export growth, also filtered for cyclical factors [14][22] 3. Lagging indicators include CPI and PPI growth, filtered similarly [14][28] 4. The model identifies the current economic state based on the trends of these indicators. For example, the "Recovery" state is characterized by rising leading indicators, stable coincident indicators, and declining lagging indicators [10][11] - **Model Evaluation**: The model improves upon the Merrill Clock by incorporating financial data, but it cannot fully capture real economic states during extraordinary events [13] 2. A-Share Pricing Framework - **Model Construction Idea**: The pricing framework integrates short-term fundamentals, long-term confidence, and required return rates to determine the reasonable valuation range of A-shares. It emphasizes the PB-ROE relationship for valuation assessment [52][56] - **Model Construction Process**: 1. Decompose stock returns into components: dividend yield, net asset growth, and valuation changes [56] 2. Use a two-stage DDM model to calculate reasonable PB values: $$PB_{current} = ROE_1 \times d_1 \times \sum_{t=1}^{T} \frac{(1+g_1)^{t-1}}{(1+R_f+R_p)^t}$$ $$PB_{stable} = \frac{ROE_2 \times d_2}{1+R_f+R_p-g_2} \times \frac{(1+g_1)^T}{(1+R_f+R_p)^T}$$ where \(ROE_1\) and \(ROE_2\) are the return on equity for the current and stable growth phases, \(d_1\) and \(d_2\) are dividend payout ratios, \(g_1\) and \(g_2\) are growth rates, and \(R_f+R_p\) is the required return rate [56][57] 3. Historical calibration suggests an 11-year duration for the first growth phase, with ROE assumptions adjusted for optimistic, neutral, and pessimistic scenarios [58] - **Model Evaluation**: The framework effectively captures valuation dynamics, but short-term ROE fluctuations introduce uncertainty [56][58] 3. Interest Rate Pricing Framework - **Model Construction Idea**: A three-factor model for long-term government bond yields, incorporating policy rates, inflation expectations, and growth expectations [59] - **Model Construction Process**: 1. Represent policy rates using one-year interbank CD rates, inflation expectations using CPI growth, and growth expectations using PMI levels [59] 2. Regression analysis reveals the relative importance of these factors: monetary policy > inflation expectations > growth expectations [62][63] 3. Additional analysis links bond yields to housing prices, reflecting cyclical economic drivers [67][69] - **Model Evaluation**: The model highlights the dominant role of monetary policy but acknowledges limitations in capturing short-term market dynamics [63][67] 4. Gold Pricing Framework - **Model Construction Idea**: Gold pricing is influenced by its commodity, financial, and monetary attributes, with monetary factors being the most consistent driver [74][75] - **Model Construction Process**: 1. Historical analysis identifies three gold bull markets driven by different factors: inflation and oil prices (1971-1980), financial crises and low real rates (2001-2011), and de-globalization and central bank purchases (2019-present) [74] 2. Introduce a valuation metric: - Pre-2022: Global gold reserves × gold price / US M2 - Post-2023: Global gold reserves × gold price / weighted M2 of reserve currency countries (USD, EUR, GBP, JPY, RMB) [80] - **Model Evaluation**: The framework effectively captures long-term trends but faces challenges in predicting short-term price movements [78][80] --- Model Backtesting Results 1. Pring Cycle - Current state: Recovery phase, favoring equity assets [35] 2. A-Share Pricing Framework - Reasonable PB range for CSI 800: 1.36-1.55 - Expected annual return: 5%-9% [58][59] 3. Interest Rate Pricing Framework - Predicted 10-year government bond yield: 1.36%-1.51% - Yield corridor: ±1.5 standard deviations around the central estimate [72][73] 4. Gold Pricing Framework - Current valuation percentile: 39% (10% below the median) - Long-term upward potential remains [80][82] --- Quantitative Factors and Construction Methods 1. Style Factors - **Value Style**: - ROE: 9.14% - PB range: 0.9-0.95 - Expected return: 6%-8% [96][100] - **Growth Style**: - ROE: 12.48% - PB range: 1.69-3.24 - Expected return: -7%-13% [103][108] - **Small-Cap Style**: - ROE: 5.99% - PB range: 0.65-1.82 - Expected return: Low [111][116] - **Large-Cap Style**: - ROE: 10.21% - PB range: 0.92-1 - Expected return: 0%-2% [119][123] - **Quality Style**: - ROE: 14.23% - PB range: 2.34-5.35 - Expected return: 8%-39% [128][131] - **Dividend Style**: - ROE: 9.09% - PB range: 0.83-0.87 - Expected return: 11%-12% [134][138] --- Factor Backtesting Results 1. Value Style - Historical PB-ROE alignment indicates moderate valuation [100][102] 2. Growth Style - High ROE volatility leads to wide valuation ranges [108][110] 3. Small-Cap Style - Valuation driven more by liquidity than fundamentals [113][117] 4. Large-Cap Style - Valuation closely tied to fundamentals, with limited upside [123][127] 5. Quality Style - Significant valuation recovery potential [131][133] 6. Dividend Style - Stable valuation with moderate upside [138][140]
