调动部属工作积极性的实证分析，可以从以下几个方面进行：

1. 了解员工需求：根据马斯洛的需求层次理论，每个人有不同的需求。领导者需要了解员工的需求，并尽可能满足他们的需求。这样，员工会感到受到重视和认可，从而增加他们的工作积极性。
2. 设立明确的目标和期望：明确的目标和期望可以增加员工的责任感和目标感。当员工知道他们的工作对团队和公司的成功至关重要时，他们会更愿意投入时间和精力。
3. 提供培训和发展机会：培训和发展机会可以提高员工的技能和知识，帮助他们更好地完成工作任务。这样，员工会感到更有能力和自信，从而增加他们的工作积极性。
4. 提供反馈和认可：定期对员工的工作进行反馈，让他们知道他们在哪些方面做得好，哪些方面需要改进。同时，当员工取得成就时，要及时给予认可和奖励，这将激励他们继续努力。
5. 营造积极的工作环境：良好的工作氛围和团队文化可以增加员工的满意度和积极性。领导者应该努力营造一个开放、支持性的工作环境，让员工感到被接纳和支持。
6. 提供适当的工作挑战：适当的挑战可以激发员工的创新精神和积极性。领导者应该根据员工的能力和工作需求，为他们提供适当的工作挑战，让他们有机会成长和进步。
7. 倾听员工意见：让员工感到被重视和被倾听是增加他们工作积极性的一个重要方式。领导者应该定期与员工交流，了解他们的想法、意见和建议，并根据实际情况进行合理的调整。

总之，调动部属工作积极性需要领导者从多个方面入手，包括了解员工需求、设立明确的目标和期望、提供培训和发展机会、提供反馈和认可、营造积极的工作环境、提供适当的工作挑战以及倾听员工意见等。通过这些方法，可以有效地提高员工的工作积极性，增强团队的凝聚力和竞争力。
