阅读材料，完成下列耍求。

下表是改革开放后，我国个体经济发展中的有关情况。

上述表格中反映了我国改革开放后社会发展的多种趋势，概括其中的一种趋势，并结合所学知识给予说明。

材料一：新中国成立初期，我国的工业基础，特别是重工业基础非常薄弱……这种落后的经济状况只能靠优先发展重工业才能改变，只有钢铁等基础工业发展了，机器制造业的原料增多了，轻工业的装备才能保证……同时，当时的国际环境也急需我们尽快建立强大的军事工业，以增强国防力量。

材料二：为了有计划地进行社会主义建设，我国政府编制了发展国民经济的第一个五年计划。它的基本任务是：集中主要力量发展重工业，建立国家工业化和国防现代化的初步基础；相应地发展交通运输业、轻工业、农业和商业；相应地培养建设人才。

材料三：1958年8月17日，中共中央在北戴河召开政治局扩大会议，通过《全党全民为生产1070万吨钢而奋斗》的决议，从此掀起轰轰烈烈的全民大炼钢铁运动。全国几千万人上阵，大搞小高炉、土法炼钢铁、群众运动。1958年12月19日宣布，提前12天完成钢产量翻番任务，钢产量为1108万吨，生铁产量为1369万吨。实际上合格的钢只有800万吨，所炼300多万吨土钢、416万吨土铁根本不能用。估计炼钢铁在全国约损失200亿元。

材料四：十一届三中全会以来，中国工业实力显著增强，到二十一世纪初，我国的钢、煤、水泥、电视机等工业品产值已居世界第一位。同时，逐步形成了以能源、机械、化工、航空航天、纺织服装、家用电器等为主体的门类齐全、独立完整的现代化工业体系。
