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the firms committed to strictly implementing China's new energy-consumption standards and to proactively eliminate outdated, high-energy-consuming production capacity.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. 
。昨天，浙江全省大部地区高温“熄火”，仅常山一地出现高温天气。受台风“梅花”外围云系影响，舟山、宁波等地都出现了较为明显的降水。

B | 据中央气象台消息，今晨5时，今年第12号台风“梅花”加强为强台风级，其中心位于浙江省象山县南偏东方向大约490公里的海面上，中心附近最大风力有14级（42米/秒）。预计，“梅花”将以每小时10-15公里的速度向偏北转西北方向移动，强度还将有所加强，逐渐向浙江温岭到舟山一带沿海靠近，并将于14日下午至夜间在上述沿海地区登陆（台风级或强台风级，38-45米/秒，13-14级）；登陆后，“梅花”将继续向西北方向移动，强度逐渐减弱。浙江省气象台预计， 受台风“梅花”外围云系影响，今天宁波、舟山、绍兴、台州、嘉兴、杭州东部等地部分暴雨，局部大暴雨。来源：中国天气网明天是降雨的核心影响时段，浙江各地雨势将增强，浙北和浙中的东部地区有暴雨，部分大暴雨，局地特大暴雨。后天，浙西北地区部分中到大雨，局部暴雨。今天下午起，浙江沿海的风力也将增强。预计，浙江中部北部沿海海面： 东北风7-8阵风9级并逐渐增强到8-9阵风10级，明天东到东北风10-12级并继续增强到13-15级，局部16级以上。浙江南部沿海海面： 偏北风7级阵风8-9级并继续增强到8-9级阵风10级，明天西北风转西南风并继续增强到10-12级。杭州湾水面： 东北风6-7阵风8级并逐渐增强到7-8阵风9级，明天东到东北风9-17级并继续增强到11-13级，局部14级以上。气象部门提醒，浙江明天将进入风雨影响核心时段，当地公众需密切关注台风预警预报信息，过往船只及时回港避风。返回搜狐，查看更多责任编辑：
