Eight Chinese leading polysilicon producers have issued public pledges to stop selling solar products below a cost benchmark, in a fresh industry effort to curb "involution-style" competition and support healthier pricing in the country's photovoltaic supply chain, the Shanghai Securities Journal reported on Friday. 
Industry experts said that this move will not only help stabilize profits across the sector, but also promote the Chinese photovoltaics (PV) industry's shift toward high-quality development.
The eight companies jointly committed that the selling prices of all photovoltaic products, including tender bids, must not fall below the corresponding cost calculated under the group standard General Principles for Cost Accounting Models in the Photovoltaic Industry. Any sales below full cost must be "immediately stopped and corrected," according to the report.
The pledge was signed in Shanghai on Thursday by the companies, including four listed companies — Tongwei Solar Co, GCL Technology Holdings Limited, Daqo New Energy Co, Xinte Energy Co. The other four companies are Asia Silicon (Qinghai) Co, Xinjiang East Hope New Energy Co, Qinghai Lihao Qingneng Co, and Xinjiang Goens Energy Technology Co.
Together, the eight companies account for more than 90 percent of China's effective polysilicon production capacity, the Shanghai Securities Journal report said.
Under the initiative, the companies also agreed to accept supervision and inspections from market regulators at all levels and to strengthen mutual oversight. If they discover illegal below-cost sales, they are required to report the issue and file complaints with the industry association and the State Administration for Market Regulation (SAMR).
In addition, the firms committed to strictly implementing China's new energy-consumption standards and to proactively eliminate outdated, high-energy-consuming production capacity.
The move comes just one week after the SAMR held a solar industry price-compliance meeting on July 31, urging solar PV companies to strengthen price compliance and shift competition from price to quality.
It instructed companies to strengthen cost accounting, establish and improve price compliance systems, and carry out comprehensive self-inspections and corrective actions, according to the Xinhua News Agency.
Industry experts welcomed the initiative, saying that years of excessive competition have pushed many photovoltaic firms into losses, which is harmful to the industry's long-term development.
China's PV industry is mired in severe low-price competition, with profit margins squeezed along the entire value chain and many firms operating at a loss, Xiang Ligang, director-general of the Zhongguancun Modern Information Consumer Application Industry Technology Alliance, told the Global Times on Friday.  
Xiang added that the initiative could help ensure more reasonable revenue and profit levels, which are essential for sustainable industrial development. The move also reflects a broader shift among Chinese firms toward greater coordination in responding to market pressures. 
Although the industry also faces external challenges, including US tariffs on polysilicon-related products, Xiang said the main purpose of the initiative is to improve the sector's own development model rather than simply respond to foreign trade measures.
China has launched sweeping efforts to curb "involution-style" low-price competition and accelerate the phase-out of outdated industrial capacity. China's Ministry of Industry and Information Technology on July 3 held a symposium for manufacturing enterprises, focusing on accelerating the high-quality development of the photovoltaics industry, according to the Xinhua News Agency. 
The symposium called for efforts to comprehensively deal with the problem of disorderly price competition in the photovoltaics industry in accordance with laws and regulations, as well as efforts to guide enterprises to improve product quality, phase out backward production capacities in an orderly manner and achieve healthy and sustainable development, Xinhua reported. 
。这款被内部寄予厚望的旗舰产品，预计将搭载尺寸接近7英寸的超大屏幕，成为苹果历史上屏幕尺寸最大的常规直屏iPhone。

二 |          据透露，苹果目前正在测试一块物理尺寸约为6.96英寸的屏幕，该方案大概率将由iPhone 20 Pro Max首发。尽管这一尺寸较现款6.9英寸的Pro Max仅有小幅提升，但苹果计划通过进一步收窄边框，使其在视觉上实现更大的屏占比。

三 |          作为iPhone问世20周年的里程碑之作，这款新机预计将复刻2017年iPhone X的设计策略。

四 | 在外观形态上，苹果计划彻底放弃沿用多年的纯直屏设计，转而采用四微曲屏方案。配合屏下Face ID与屏下前置摄像头技术，新机正面将实现近乎无边框的真全面屏效果，彻底告别刘海与灵动岛。同时，机身侧边的实体按键将被固态触控按键取代，通过震动马达提供拟真触感反馈，进一步强化机身的一体化设计。

五 |          在核心配置方面，20周年纪念版iPhone有望首发搭载基于台积电2nm制程工艺的A21 Pro芯片，并可能引入苹果自研的LOFIC传感器，大幅提升影像系统的动态范围。

六 | 此外，机身材质也有望回归一体化全玻璃设计，中框改为弧形过渡，以配合四微曲屏实现更流畅的视觉与握持体验。         目前，这款7英寸超大屏仍处于早期的工程验证（EVT/DVT）阶段，最终量产方案仍可能根据测试结果进行调整。（青云）。
