Zhou Jiang, a researcher at the Sichuan Academy of Social Sciences, has a favorite book:  White Deer Tableland or Bai Lu Yuan by renowned writer Chen Zhongshi.
As vice president of the Regional Science Association of China (RSAC), Zhou told the Global Times that a lifetime of reading has profoundly shaped the way he sees and understands the world. It ultimately led him to a career in research and academia, where he teaches and pursues scholarly work.
Since earning his PhD in economics in 2000, he has devoted himself to the study of regional science and economics, a field that demands a constant crossing of disciplinary boundaries, drawing on the fields of geography, sociology, history, and ecology among others.
"Reading has kept alive my sense of curiosity and taught me to ask questions with patience and persistence: Where do disparities in regional development come from? How do policies affect different groups in society? And how can a region pursue both efficiency and equity so that development is not merely effective, but also imbued with a greater sense of humanity and warmth?" Zhou noted. 
Founded in 1991, RSAC is a national academic society dedicated to advancing domestic and international academic exchange and cooperation, providing consulting services on spatial planning, urbanization, and regional development, and offering intellectual support for China's modernization drive.
The 57-year-old researcher noted that reading has empowered him in two distinct ways.
"The first is discernment. When confronted with a complex issue, I try not to settle for a simple conclusion. Instead, I make an effort to understand its broader context, how it has unfolded, and the perspectives of the different people involved," he said. 
"The second is a sense of inner steadiness. Setbacks are an inevitable part of both life and work. Good books remind us that hardship is never ours alone to bear; countless people before us have faced circumstances more difficult than our own, made difficult choices, and found the strength to carry on. Reading cannot solve every problem for us, but it can help us remain calm when challenges arise, giving us the clarity and resilience that allow us not to panic or give up too easily," he said. 
Historical depth

Each time Zhou returns to the White Deer Tableland, he finds something different in its pages. 
"When I first read it as a young person, I was drawn primarily to the characters and the twists and turns of their lives. Later, as I began researching regional economics, I found myself paying closer attention to the changes in the land, the countryside, families and social order presented in the story. Now, approaching 60, I have come to appreciate more deeply the choices the characters make, the constraints they face, and the quiet perseverance they show amid the sweeping currents of their times," he said. 
White Deer Tableland uses Bai Lu village in Northwest China's Shaanxi Province as a microcosm, tracing the feuds and intertwined fortunes of three generations of the Bai (literally meaning white) and Lu families. Through their stories, it captures more than half a century of sweeping historical change, from the final years of the Qing Dynasty (1644-1911) to the 1970s and 1980s. The novel won the Mao Dun Literature Prize, one of China's top literature awards, in 1997.
Zhou prefers literary works with historical depth and a keen eye for social change. 
Regional economics may appear to be concerned with the spatial distribution of industries, population and resources, but at its heart, it is about how people live on a particular piece of land, and why some places flourish while others decline, he noted. 
In this sense, literature and history are more than pastimes beyond professional research. They often help him understand the historical context, cultural traditions and social mentality that lie behind economic data, he said. 
When reading novels, Zhou said that he often pays close attention to the relationship between people and the places they inhabit: How the land shapes the local character, how transportation transforms a region, and how shifts in industry reshape families and villages. Such details may not offer a direct conclusion, but they broaden a researcher's perspective. They also serve as a reminder that research should look beyond growth rates and statistical indicators to consider the sense of fulfillment experienced by ordinary people and the dignity of human beings.
Understanding ourselves
Once, while tidying his study, he came across a book filled with notes he had scribbled in his early years. Among them was a question that particularly caught his attention: "In the face of sweeping changes in the times and profound social transformation, what can a person truly determine for himself?"
Looking at those words he had written in his youth was like coming face to face with the person he had been decades ago.
Reading is not simply the act of understanding a book; it is also a record of a person's own growth, he said. The same book can reveal something entirely different when read at different stages of life. 
When we are young, we turn to books in search of answers; but when we become seasoned, we read more to understand life, to understand others, and ultimately, to better understand ourselves, Zhou said. 
In this era of fragmented information, AI can help people access information quickly, organize materials, and gain a basic understanding of unfamiliar fields. Yet deep reading, Zhou said, allows people to see how a conclusion is reached — what evidence supports it, where its boundaries lie, and what alternative interpretations it may invite.
What truly shapes a person, after all, is not how much information they have browsed, but the words that have made them pause and reflect - and the words that have remained with them for many years, he added. 
。         报道指出，三家存储巨头此举主要是为了避免陷入“自我侵蚀”（cannibalization）的两难境地：若强行向市场推广自研的高端CXL控制器芯片，反而可能蚕食其核心利润来源——通用DRAM（DIMM）的市场需求。目前，这三家巨头正迅速从自主设计路线，转向采用专业无晶圆厂（Fabless）企业芯片的外包体系。

B |          各自路线调整：从自研到外购          据半导体业界消息，三星电子、SK海力士、美光均已缩减或搁置了用于CXL扩展设备的控制器商用化计划，原本由它们自研填补的市场空间，正被Montage（澜起科技）、Astera Labs、PrimeMass等无晶圆厂企业快速填充。         其中，美光是最先放弃自主研发的厂商。该公司已解散其独立的CXL控制器研发团队，并全面采用PrimeMass的解决方案。目前，在美光的产品目录中，也已同步出现PrimeMass的解决方案。         SK海力士近期则正式向其主要合作伙伴通报，将停止CXL控制器的自研项目。公司正将相关研发人员重新调配至新一代运算用内存半导体——PIM（Processing In Memory，存内处理）领域，意图将有限的研发资源集中于更具确定性的未来增长点。         三星电子的策略调整更为微妙。公司将其自主研发的CXL控制器从开发团队中剥离，仅保留用于内部研究。该团队目前的研究方向已转向基于LPDDR（低功耗DRAM）的CXL解决方案等尚未经过验证的领域。而在对外销售时，三星将采购并使用无晶圆厂企业的控制器。

C |          这与三星电子最初的蓝图大相径庭。三星原计划推出结合自研控制器与CMM（CXL Memory Module）的模组产品，但其自研控制器的正式产品化计划现已从官方路线图中删除。一位熟悉情况的半导体业界人士透露：“三星内部的产品规划部门已将自研控制器从正式商品化课题中移除，仅保留为先行研发课题。目前团队仅围绕移动DRAM与CXL结合等短期内商用化不明朗的领域进行研究，这实际上已转向市场探索阶段。”          “一体化”与“分立式”的商业模式冲突          报道分析认为，存储三巨头战略转向的根本原因，在于其最初构想的商业模式与客户需求发生了根本性冲突。         三家厂商最初的构想是销售类似“一体化CXL模组”的高附加值产品，即将自研控制器芯片与DRAM集成于同一基板，作为高价成品供应。

D | 然而，主要数据中心客户为节省庞大的基础设施建设成本，却强烈倾向于“分立式”结构：即在系统主板上单独搭载CXL控制器，并在后端插槽中插入市场上常见、价格低廉的通用DRAM（DIMM）进行再利用。         这种矛盾直接触发了“自我侵蚀”风险。若内存厂商强行推广高价一体化产品，客户将可能减少采购，同时，原来大量出货的通用DRAM需求也可能随之萎缩。         一位半导体业界人士分析称：“从内存制造商的角度看，若自家CXL扩展设备成品需在市场上与核心‘现金牛’DIMM产品正面竞争，业务便难以大力推进。

E | 管理层的冷静判断是，在承担冲突风险下强行商业化自研控制器并无实际利益。”          回归生态分工，并非技术退缩          专家强调，不应将三巨头的这一集体行动解读为对CXL技术或市场的退缩与放弃，而应视为在不确定的市场初期阶段化解风险，并回归半导体生态系统高效分工的理性选择。         另一位业界人士指出：“相较于强行独揽CXL主导权，他们选择了与无晶圆厂企业互利共赢的分工模式。”并预测道：“未来，随着全球半导体市场不断深化发展，由专业无晶圆厂企业负责设计、存储厂商专注制造这一最优生态分工趋势预计将加速。”          编辑：芯智讯-林子。
