3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 在12月4日由中國(guó)煤炭工業(yè)協(xié)會(huì)主辦，中國(guó)煤炭運(yùn)銷協(xié)會(huì)、日照市人民政府承辦的2020年度全國(guó)煤炭交易會(huì)上，中國(guó)煤炭工業(yè)協(xié)會(huì)黨委書記、會(huì)長(zhǎng)梁嘉琨表示，新中國(guó)成立70年來(lái)，我國(guó)煤炭供給體系質(zhì)量明顯提升，產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、轉(zhuǎn)型升級(jí)取得重要突破，煤炭市場(chǎng)化改革穩(wěn)步推進(jìn)，勞動(dòng)生產(chǎn)率顯著提升，生態(tài)文明礦區(qū)建設(shè)取得顯著成效，煤礦安全生產(chǎn)形勢(shì)持續(xù)好轉(zhuǎn)。
但制約煤炭行業(yè)高質(zhì)量發(fā)展的瓶頸問(wèn)題依然突出，主要表現(xiàn)在：一是煤炭應(yīng)急供應(yīng)保障難度加大；二是煤炭經(jīng)濟(jì)運(yùn)行存在下行壓力；三是體制機(jī)制創(chuàng)新與供給側(cè)結(jié)構(gòu)性改革協(xié)同效應(yīng)有待提高；四是煤炭企業(yè)稅費(fèi)負(fù)擔(dān)重的問(wèn)題突出；五是老礦區(qū)煤炭企業(yè)轉(zhuǎn)型發(fā)展面臨諸多困難。
梁嘉琨指出，總體來(lái)看，今年以來(lái)煤炭消費(fèi)增速放緩，預(yù)計(jì)全年煤炭消費(fèi)將保持小幅增長(zhǎng)，煤炭產(chǎn)量保持穩(wěn)步增長(zhǎng)，全國(guó)煤炭市場(chǎng)供需已由總體平衡向?qū)捤煞较蜣D(zhuǎn)變。
但值得注意的是，煤炭應(yīng)急供應(yīng)保障難度加大。
一方面，電力供需結(jié)構(gòu)性變化帶來(lái)峰谷差加大，大中型城市最大峰谷差占最大負(fù)荷的比重接近50%，隨著清潔能源發(fā)電比例不斷提高，煤電受季節(jié)極端天氣的影響越來(lái)越大，調(diào)峰壓力在加大。
另一方面，煤炭產(chǎn)業(yè)布局和區(qū)域供應(yīng)格局持續(xù)變化，煤炭生產(chǎn)進(jìn)一步向晉、陜、蒙、寧、新集中，一些傳統(tǒng)的煤炭調(diào)出省變成調(diào)入省，加之“公轉(zhuǎn)鐵”的實(shí)施，煤炭調(diào)出的規(guī)格、布局變化很大。
梁嘉琨強(qiáng)調(diào)，以上困難和問(wèn)題的解決需要進(jìn)一步鞏固煤炭供給側(cè)結(jié)構(gòu)性改革成果，堅(jiān)守“中長(zhǎng)期合同制度”和“基礎(chǔ)價(jià)+浮動(dòng)價(jià)”的定價(jià)機(jī)制，加強(qiáng)煤炭市場(chǎng)研究，依法依規(guī)組織生產(chǎn)經(jīng)營(yíng)，強(qiáng)化行業(yè)自律和誠(chéng)信經(jīng)營(yíng)，保障煤炭經(jīng)濟(jì)長(zhǎng)期平穩(wěn)運(yùn)行。
